s is the length of the side of the square. |

Rectangle | P=2L+2W | L and W are the lengths of the rectangle’s sides (length and width). |

Triangle | a+b+c | a,b , and c are the side lengths. |

Also, How do we calculate area?

The simplest (and most commonly used) area calculations are for squares and rectangles. 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.

**How do you find the length and area of a rectangle?**

To find Length or Breadth when Area of a Rectangle is given

- When we need to find length of a rectangle we need to divide area by breadth.
- Length of a rectangle = Area ÷ breadth.
- ℓ = A ÷ b.
- Similarly, when we need to find breadth of a rectangle we need to divide area by length.
- Breadth of a rectangle = Area ÷ length.

**What are three ways to find the area of a rectangle?**

Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: **A = L * W** where A is the area, L is the length, W is the width, and * means multiply.
