What is the area of the figure?


What is the area of the figure? The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc.

How do you find the area of a figure? To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

What is the area of this irregular figure? Area of the given irregular shape = Area of the rectangle ‘P’ + Area of the semicircle ‘Q’ + Area of the triangle ‘R’ + Area of the rectangle ‘S’. ⇒ Area of the given irregular shape = 48 + 39.25 + 24 + 48 = 159.25 square units. Therefore, the area of the given irregular shape is 159.25 square units.

What is an example of finding the area of a shape? Area of a Rectangle

In the above example, the length of the rectangle is 3 units and the width is 2 units. The area of a rectangle is obtained by multiplying its length and width which is the same as counting the unit squares. Thus, the formula for the area of a rectangle is: Area of the rectangle = length × width.

What is the area of the figure? – Related Questions

What is an area formula?

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

What is an irregular figure in math?

An irregular figure is a figure that is not a standard geometric shape. Its area cannot be calculated using any of the standard area formulas. But some irregular figures are made up of two or more standard geometric shapes.

How do you find the area of an unusual shape?

Ans: To find the area of irregular shapes, first we need to divide the irregular shape into regular shapes that you can recognize such as triangles, rectangles, circles, squares etc. Then, find the area of these individual shapes and add them up to get the area of irregular shapes.

How do you find the area of an irregular shape with 4 sides?

The area of any irregular quadrilateral can be calculated by dividing it into triangles. Example: Find the area of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.

What is area example?

Area is a measure of how much space there is on a flat surface. For example, in a rectangle we find the area by multiplying the length times the width. In the rectangle above, the area is 2×4 or 8. If you count the small squares you will find there are 8 of them.

What’s the formula for calculating the area of a circle?

The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.

What is perimeter formula?

The perimeter is equal to the boundary of the rectangle which can be calculated with the formula: Perimeter = Length + Length + Width + Width = 2(Length + Width).

Why is area squared?

Why is the area of a square a side square? A square is a 2D figure in which all the sides are of equal measure. Since all the sides are equal, the area would be length times width, which is equal to side × side. Hence, the area of a square is side square.

How do you find irregular shapes?

Areas of irregular figures can be determined by dividing the figure into squares and rectangles. Some irregular figures are made of rectangular or square regions. The areas of such irregular figures can be determined by calculating the areas of these rectangles and squares.

What 3D shapes do Year 1 need to know?

What 3D shapes do children need to know in Year 1? The National Curriculum for Year 1 states that children should be able to name 3-D shapes for example, cuboids (including cubes), pyramids and spheres.

How do you know if a shape is regular or irregular?

Regular shapes have sides that are all equal and interior (inside) angles that are all equal. Irregular shapes have sides and angles of any length and size.

What is the difference between area and perimeter?

The perimeter of a shape represents the distance around it, the area of a shape is the surface or flat space that the shape covers (in 2D) while the volume of a shape is the space it occupies in real life (in 3D).

How do you find the area of a shape with 5 sides?

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.

How do you calculate area and perimeter?

Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 ÷ 4 = 3.5.

Is Circle an irregular shape?

Is a circle a regular shape or an irregular shape? So yes, a circle is about as regular as a shape can be. You can define a circle with just a center and a radius. Compare this, for example, to the shape of a human body, which would be rather irregular, requiring a lot of information to describe it fully.

What is a regular and an irregular shape?

Use mathematical language to explain the difference between regular and irregular shapes. Regular shapes have sides and angles that are all equal. Irregular shapes have sides and angles of different measures.

What is an irregular Heptagon?

A heptagon is a seven-sided polygon. Along with seven sides, a heptagon has seven vertices and angles. A regular heptagon is a heptagon that has congruent sides and angles. An irregular heptagon is any heptagon with sides and angles that are not all congruent.

What shape has 4 sides with different lengths?

Quadrilaterals are polygons with four sides (hence the beginning “quad”, which means “four”). A polygon with non-equal sides is called irregular, so the figure that you are describing is an irregular quadrilateral.

Where do we use area in real life?

What real-life situations require us to use area? ▫ Floor covering, like carpets and tiles, require area measurements. Wallpaper and paint also call for area measurements. Fabric used for clothing and other items also demand that length and width be considered.

How do you describe a circle shape?

A circle is a round shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

What is perimeter and area of square?

Answer: The area of a square is equal to the square of the length of its side and the perimeter of the square is 4 times the length of its side. Let the length of the side of a square be ‘a’ units. Explanation: The area of the square = a² square units. The perimeter of the square = 4a units.
