Answer:
x = 5
Step-by-step 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.
