Question

A triangle has an area if 50cm^2 if the length of its sides are all reduced by a scale factor of 30% calculate the area of the reduced triangle

Answer 1

Given 
area of triangle = 50^2
sides reduced = 30%
find - area reduced 

30% of area = 30/100 * 50
= 15cm^2
Area reduced = 50 - 15
=35cm^2
