Given the following shapes: a rectangle with width 4 and height 1, a rectangle with width 3 and height 7, a trapezoid with bases 7 and 5 and height 4, a trapezoid with bases 9 and 6 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 4 and height 1: Area = 4 x 1 = 4
Rectangle with width 3 and height 7: Area = 3 x 7 = 21
Trapezoid with bases 7, 5 and height 4: Area = 0.5 x (7 + 5) x 4 = 24.0
Trapezoid with bases 9, 6 and height 4: Area = 0.5 x (9 + 6) x 4 = 30.0</think>
