Given the following shapes: a trapezoid with bases 1 and 4 and height 7, a trapezoid with bases 3 and 2 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 1, 4 and height 7: Area = 0.5 x (1 + 4) x 7 = 17.5
Trapezoid with bases 3, 2 and height 1: Area = 0.5 x (3 + 2) x 1 = 2.5</think>
