Given the following shapes: a square with side 2, a square with side 3, a square with side 1, a trapezoid with bases 7 and 1 and height 9. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Square with side 2: Area = 2^2 = 4
Square with side 3: Area = 3^2 = 9
Square with side 1: Area = 1^2 = 1
Trapezoid with bases 7, 1 and height 9: Area = 0.5 x (7 + 1) x 9 = 36.0</think>
