Answer :
The linear scale factor is used to reduce or enhance the size of the original measures. The base of the reduced triangle is 8. Thus, option b is correct.
What is a linear scale factor?
The linear scale factor is the reduction or the enlargement of the size like the width, height, base, length, etc. of the geometrical shape.
Given,
The height of the original triangle = 12
The base of the original triangle = 24
The linear scale factor reduces the original size by 1/3 factor.
The 1/3 factor of the base will be = 24 ÷ 3 = 8
Therefore, option b. 8 is the base of the reduced triangle.
