Question

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

Answer 1

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

Answer 2

Answer:

13 ft

Step-by-step 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 = $b^{2}$

$b$ = $\sqrt{169}$

$b$ = 13
