Given the following shapes: a trapezoid with bases 3 and 3 and height 1, a trapezoid with bases 2 and 5 and height 6, a trapezoid with bases 5 and 7 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 3, 3 and height 1: Area = 0.5 x (3 + 3) x 1 = 3.0
Trapezoid with bases 2, 5 and height 6: Area = 0.5 x (2 + 5) x 6 = 21.0
Trapezoid with bases 5, 7 and height 3: Area = 0.5 x (5 + 7) x 3 = 18.0</think>
