Given the following shapes: a rectangle with width 3 and height 1, a trapezoid with bases 1 and 6 and height 8, a square with side 1, a square with side 3, a square with side 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 3 and height 1: Area = 3 x 1 = 3
Trapezoid with bases 1, 6 and height 8: Area = 0.5 x (1 + 6) x 8 = 28.0
Square with side 1: Area = 1^2 = 1
Square with side 3: Area = 3^2 = 9
Square with side 3: Area = 3^2 = 9</think>
