Question

The length of a square is 4y + 7. What is the perimeter of the square?

Answer 1

Explanation:

Perimeter of a square = 4 * Length of the square

Given

Length of a square = 4y + 7

Perimeter of the square = 4(4y+7)

Open the parenthesis

Perimeter of the square = 4(4y)+4(7)

Perimeter of the square = 16y + 28

Hence the perimeter of the square is 16y+28
