Question

can someone help me

Answer 1

Call the area of ABC like Sabc and the area of ADE like Sade.

The ratio of similarity of the triangles ABC and ADE it's 4/10 = 2/5.
So the ratio of the areas it's the square of it, 4/25

So, Sabc / Sade = 4/25

Sade = 50, Sabc/50 = 4/25
Sabc = 8

Area of the trapezoid it's the ADE area minus ABC area = 50 - 8 = 42.
