Area of a square

A square is a parallelogram with 4 congruent sides and 4 right angles.

Area of a square

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

$Area=s\;\cdot\;s\;\;\;\;\;\;That\;is:\;\;A=s\fs2^2$

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=4?
