Question

Can someone help me find the area of this shaded shape?

Answer 1

First you find the ratio of the heights

So you do 2/6, which simplifies to 1/3

Then you square 1/3 and get 1/9

Then you set 1/9 equal to 20/x

Finally you cross multiply to get equation x=180

So, the area of the shaded polygon is 180 in^2
