Question

The perimeter of a square is (8x + 6) centimeters. Part A: Write an expression for the length of a side of the square. Part B: The perimeter of the square is 72 centimeters. Write and solve an equation to find the value of x, then find the side length of the square.

Answer 1

Explanation:

Part A:

(8x+6)/4= 2x+ 1.5

Part B:

72= (8x+6)

8x= 72-6

8x= 66

x= 8.25

the side length = 2x+1.5= 2(8.25)+1.5= 18 centimetres
