Question

A picture frame has an area of 121 square centimeters. Assuming it is a square, what is the perimeter of the frame?

Answer 1

P =44 cm

Explanation:

The area of a square is given by

A = s^2 where s is the side length

121 = s^2

Taking the square root of each side

sqrt(121) = sqrt(s^2)

11 = s

We want to find the perimeter of a square

P = 4s where s is the side length

P = 4(11)

P =44 cm
