Question

The area of a square is 144 square centimeters. what is the length of one side of the square?

Answer 1

A = a^2
144 = a^2
sqrt 144 = a
12 = a.....each side of the square is 12 cm

Answer 2

The length of one of the side of the square is 12 cm.

Explanation:

Area of the Square = 144 cm²

let s be the side of the square.

According to the question,

`s* s=144`

`s^2=144`

`s=\pm\sqt{144}`

`s=\pm12`

negative value of s is rejected as side can never be negative.

Therefore, The length of one of the side of the square is 12 cm.
