Question

A square park has an area of 900m^2. How can you use a square root to determine the side length of park?​

Answer 1

side length = 30 m

Explanation:

the area (A) of a square is calculated as

A = s² ( s is the side length )

given A = 900 , then

900 = s² ( take square root of both sides )

`√(900)` =
`√(s^2)` , that is

30 = s

the side length of the park is 30 m
