Answer 1

@Hero

Answer 2

Do you think that these triangles are proportional?

Answer 3

you are told the triangles are similar..

so you need to find the scaling factor

find the area of the large triangle using


A = 1/2 bh

there is a property about the area of similar shape... the ratio of the areas is the linear ratio squared.

so

Area of small = area of large x (scaling factor)^2

hope it helps
