CPM Homework Help : INT2 Problem 9-112

Two similar trapezoids in centimeters. The first trapezoid, E, K, I, M, has a bottom base M, L, and a top base, E, K. A perpendicular line drawn from E to base, M, l, has a length of 33. The second trapezoid M, A, E, T, has bottom base, T, E, of 30, and top base, M, A, of 20. A perpendicular line drawn from M to base, T, E, has a length of 11. The trapezoids at right are similar.

What is the ratio of the heights? Hint: It is not $3$ or $\frac { 1 } { 30 }$ .
Hint (a):
Refer to the Math Notes box.
Compare the areas. What is the ratio of the areas?
Hint (b):
Use proportional equations to find the missing dimensions.
Refer to the Math Notes box.
More Help (b):
The formula to find the area of a trapezoid is $\frac{1}{2}h(b_1+b_2)$
