Area of a square

If s is the side-length of a square, the area of the square is:

What is the area?

Find the side length of the square.

side: 13 yd

Use this number in the formula.

Area = side × side
= 13 × 13
= 169

Now find the units. The lengths are measured in yards, so the area is measured in square yards.

The area is 169 square yards.

What is the area when s=5?
