If triangle CDE is dilated by a scale factor of 1/5 with a center of dilation at vertex E, what is the area of triangle C'D'E'?

timurjin [86]

The correct answer would be Choice B: 4 square units.

When the scale factor is 1/5, that means the lengths of the sides are 1/5 of the original size. So instead of having a base of 20 and height of 10, the new triangle has a base of 4 and a height of 2.

The area of the triangle is: (4 x 2) / 2 = 4

First take the fractions and find their common denominator:
$\frac{1}{2}$ x 4 = $\frac{4}{8}$

Now you can add the fractions:
$\frac{4}{8} + \frac{1}{8} = \frac{5}{8}$

Now add your whole numbers and the fraction:
1+1= 2 >> 2+ $\frac{5}{8}$ = 2 $\frac{5}{8}$ yards

Now subract 2 $\frac{5}{8}$ from 5:
5-2 $\frac{5}{8}$ =2 $\frac{3}{8}$ yards
