Question

A square has a perimeter of 12x + 52 units. Which expression represents the side length of the square in units?

a) x + 4
b) x + 40
c) 3x + 13
d) 3x + 43

Answer 1

C

Explanation:

If a square has 4 sides and the perimeter is 12x + 52, you have to divide 12x + 52 by 4 to get the length of a single side

12x / 4 = 3x

52 / 4 = 13

3x + 13
