A square patio rug has side lengths of 1/3(x+2) inches

Question

a. Write a linear expression involving the perimeter of the square, P in terms of x.

b. Solve for x in terms of P.

Answer 1

a square has FOUR equal sides

4 * 1/3(x+2) = 4/3 x + 8/3 = P

4/3 x = P - 8/3

4 x = 3 P - 8

x = 3/4 P - 2
