Alice wants to put wall-to-wall carpeting in a small room with the floor plan shown.
a. alice says she can find the area of the room by dividing the floor plan into two trapezoids. show how she can divide the floor plan. then find the area using her method.

I found the complete problem.

If Alice divides it into two trapezoids, the area formula would be: A = [(a+b) / 2] * h
Trapezoid 1
A = [(7.5 + 15)/2 * 5
A = (22.5/2) * 5
A = 11.25 * 5
A = 56.25 sq. ft

Trapezoid 2
A = [(5 + 10)/2 * 7.5
A = (15/2) * 7.5
A = 7.5 * 7.5
A = 56.25 sq. ft

Total area = 56.25 + 56.25 = 112.50 sq. ft.
