Question

A garden has four sides that are all the same length. Each side measures x+4 units. The garden's perimeter is 112 units.

What is the value of x?

Answer 1

Divide the perimeter by 4 to get the length of a side:

112/4= 28

Now solve for x:

X + 4 = 28

Subtract 4 from both sides:

X = 24
