Question

The length of a rectangle is 4 cm greater than the width of the rectangle.

If the area of the rectangle is 45 square cm, what is the length of the
rectangle?

A) 9 cm
B) 4 cm
C) 5 cm
D) 13 cm

Answer 1

answer: a) 9 cm

explanation: since the length of the rectangle is 4 cm greater than the width, you can just take 9 cm (the length) minus 4, which gets you 5 cm. if we use the area formula (length x width), then 9 x 5 = 45 square cm.
