Question

A square pool has an area of 169ft^2 . What is the side length of the pool?

Answer 1

13 ft

Explanation:

The area of a pool is length × width (l × w) , but the length and width are the same so I'll use
`b` representing both length and width:

A = l × w

A =
`b^(2)`

Area of the pool is 169

169 =
`b^(2)`

`b` =
`√(169)`

`b` = 13

Answer 2

Area of a square is side ^2

To find the length of the side using area find the square root of the area.

Side length = sqrt(169)

Side length = 13 feet
