Question

The ratio of the longer side of a rectangle to its

shorter side is 4 to 3. If the shorter side of the
rectangle is 21 ft, what is the length of its longer side?

Answer 1

28 ft

Explanation:

Given,

The ratio of the longer side of a rectangle to its shorter side=4:3

It is said that the length of the shorter side is 21 ft.

Let the longer side be x.

Then,

4:3=x:21

or,4/3=x/21

or,x=(4*21)/3=28 ft. [ANS]
