The perimeter of the rectangle below is 94 units. Find the length of side PS.
Write your answer without variables.

Answer:
PS = 26 units
Step-by-step explanation:
Perimeter of rectangle = 94
2(4z - 2 + 3z) = 94
2(7z - 2) = 94
14z - 4 = 94
14z = 94 + 4
14z = 98
z = 98/14
z = 7
QR = 4z - 2 = 4*7 - 2 = 28 - 2 = 26
PS = QR (Opposite sides of rectangle)
PS = 26 units
