## Why Calculate Area?

The area of a square or rectangle is the amount of space that shape occupies on a flat surface. Calculating the area is essential for estimating materials, planning spaces, and making decisions when designing or building structures.

## Area of a Square

A square is a rectangle with equal sides. To calculate the area of a square, multiply the length of one side by itself (length x length) or use the formula:

**Area of Square = Length x Length**

## Area of a Rectangle

A rectangle has two opposite sides of equal length. To calculate the area of a rectangle, multiply the length by the width:

**Area of Rectangle = Length x Width**
