Question

How do you do this? ​

Answer 1

a) The ratio of the perimeters is the same as the scale factor, so the ratio is the perimeters is 2/3.

b) The perimeter of triangle ABC is $36\left(\frac{3}{2} \right)=\boxed{54 \text{ ft}}$

c) The ratio of the areas is the scale of the scale factor. In this case, the ratio is $(2/3)^{2}=\boxed{4/9}$

d) The area of FDE is $36(4/9)=\boxed{16 \text{ ft}^{2}}$
