Question

A square has a area of 81 square feet. What is the length of each side of the square

Answer 1

9 ft

Explanation:

The equation for area of a square is:

`A=s^2`

Where s represents the length of the side.

We can substitute 81 square feet for the area to solve for s...

`81ft^2=s^2`

Take the square root of both sides:

`√(81ft^2)=√(s^2)`

`9ft=s`

Therefore the length of each side is 9 ft.
