Find the length of a side of a square with an area of 169 m^2

The side length is 13 m

Step-by-step explanation:

The area of a square is given by the formula

A = s^2 where s is the side length

169 = s^2

Take the square root of each side

sqrt (169) = sqrt (s^2)

13 = s

The side length is 13 m
