Answer: 108
========================
Work Shown:
This figure is a trapezoid because it has exactly one pair of opposite parallel sides. Those parallel sides are known as the bases which we'll call b1 and b2
b1 = 1
b2 = 8
The height is 24, so h = 24.
------------
Plug b1 = 1, b2 = 8, and h = 24 into the area of a trapezoid formula below
A = h*(b1+b2)/2
A = 24*(1+8)/2
A = 24*9/2
A = 216/2
A = 108
