Question

PLEASE HELP (I'll post an image of the problem!)

Answer 1

18 + 1.5 * 18 + 1.5 * 27
= 18 + 27 + 40.5
= 85.5

Answer 2

since the ratio of BA:DE would hold for all the sides of the triangle.

The ratio of BA: BE is 1.5:1

Therefore, if you multiply all the sides of the small triangle by 1.5, you would get the sidelengths of the bigger triangle
