Question

What is the length of each side of a square if its area is 121 ft??

11 feet
12 feet
10 feet
30 feet

Answer 1

11 feet

Explanation:

Given,

Area of square ( a^2 ) = 121 ft

To find : Length of each side ( a ) = ?

Formula : -

Area of square = a^2

a^2 = 121

a = √121

a = 11 feet

Answer 2

11 ft = side length

Explanation:

The area of a square is found by

A = s^2

121 = s^2

Taking the square root of each side

sqrt(121) = sqrt(s^2)

11 = s
