## What is the area of 2D shapes?

Area Of 2 D Shapes – Definition with Examples

2D Shape Area Formula Example
Square Area of a Square = Side × Side Area = S × S Area = 4 × 4 = 16 sq. cm
Rectangle Area of a Rectangle = Length × Width = l × w Area = 8 × 3 = 24 sq. cm

## How do you calculate total area?

Multiply the length of the base, b, by the height, h, to find the total area. The equation for the area, A, of a square or rectangle area can be written as: A = b * h. In our example, the base, b, is 12 inches, and the height, h, is 5 inches. Therefore, the area is 12 inches multiplied by 5 inches, or 60 square inches.

## What is the perimeter formula?

The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers.
