Question

In a certain rectangle, the ratio of the lengths of

2 adjacent sides is 5 to 2. If the area of the rectangle is
90 square inches, what is the length, in inches, of the
longer side?
A. 6.
B. 9
C. 15
D. 18
E. 45

Answer 1

C. 15

Explanation:

The longer side is 15 and the shorter side is 6.

15*6=90

reduce 15 by dividing it by 3

=5

reduce 6 by dividing it by 3

=2

therefore, the ratio is 5:2
