Question

One side of a square is (x+3) units. The
perimeter of the square is 32 units. What
is X?

Answer 1

x = 5

Explanation:

So the perimeter of a square is 4 times the side length.

4 (x+3) = 32 is the equation we can make out with the given information.

Solve for x:

Distribute the 4 to the terms inside the parenthesis; 4x + 12 = 32

Subtract 12 from both sides; 4x = 20

Divide both sides by 4; x = 5

By isolating x, we get 5 as the value of x.
