Question

If a square has a side length of x + 4 and a perimeter of 44 cm, what is the value of x. *

Answer 1

Square are the same size all the way around, which means every side = x + 4

The perimeter of a square = 4 * side

the perimeter = 44 cm

Let's plug our values into the formula above.

44 cm = 4 * (x + 4)

Distribute the 4

44 cm = 4x + 16

Subtract 16 from both sides

28 cm = 4x

Divide both sides by 4

7 = x
