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 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 T, E, has a length of 11.The trapezoids at right are similar.
