Given the following shapes: a rectangle with width 3 and height 4, a rectangle with width 3 and height 5, a rectangle with width 7 and height 2, a trapezoid with bases 5 and 4 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 3 and height 4: Area = 3 x 4 = 12
Rectangle with width 3 and height 5: Area = 3 x 5 = 15
Rectangle with width 7 and height 2: Area = 7 x 2 = 14
Trapezoid with bases 5, 4 and height 3: Area = 0.5 x (5 + 4) x 3 = 13.5</think>
