The reduced base length is 8 units if the scale factor of 1/3 is used to make a reduction option second 8 is correct.
What is a scale factor?
The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
We have a scale factor of 1/3 is used to make a reduction.
Scale factor = 1/3
From the table, base of the triangle = 24
Reduced by factor 1/3:
Reduced base = (1/3)24
= 8 units
Thus, the reduced base length is 8 units if the scale factor of 1/3 is used to make a reduction option second 8 is correct.
