Given the following shapes: a trapezoid with bases 4 and 2 and height 3, a rectangle with width 7 and height 1, a rectangle with width 8 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 4, 2 and height 3: Area = 0.5 x (4 + 2) x 3 = 9.0
Rectangle with width 7 and height 1: Area = 7 x 1 = 7
Rectangle with width 8 and height 1: Area = 8 x 1 = 8</think>
