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((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)}`
