In the diagram, rectangle $PQRS$ is divided into three identical squares. If $PQRS$ has perimeter 120 cm, what is its area, in square centimeters?

Well, perhaps not
three squares means the length , l is divided into 3 and each of these segments is the same as the width (because of the square)
perimeter would be 6 of these segements for the sides + 2 more for the ends:
6 (1/3 l) + 2 (1/3 l) = 120
2l + 2/3 l = 120
l = 45 w = 15 three squares would be 15 x 15
pqrs area = 45 x 15 = ......... cm2
