Question

The perimeter of a square can represent by 16x + 24. Willa wants to write an equivalent expression for the perimeter that shows the side length of the square. Create an equivalent expression that Willa could write

Answer 1

Given that in a square, length=width, let the length be L, the perimeter will be:
P=L+L+L+L=4L
but
4L=16x+24
thus the length of one side will be:
L=4x+6
hence the length of the perimeter is (4x+6) units and the width is (4x+6) units.
