Given the following shapes: a trapezoid with bases 4 and 4 and height 4, a trapezoid with bases 5 and 7 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 4, 4 and height 4: Area = 0.5 x (4 + 4) x 4 = 16.0
Trapezoid with bases 5, 7 and height 4: Area = 0.5 x (5 + 7) x 4 = 24.0</think>
