If a scale factor of One-fifth is used to make a reduction, what is the base of the original triangle?

Answer 1

The reduction was 1/5.

Because you are given the reduced values, multiply the reduced value by the inverrse of the factor:

Inverse of 1/5 = 5

Height = 3 x5 = 15

Base = 5 x 5 = 25

The base is 25
