Given the following shapes: a square with side 4, a trapezoid with bases 3 and 5 and height 5, a trapezoid with bases 3 and 1 and height 9, a rectangle with width 6 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Square with side 4: Area = 4^2 = 16
Trapezoid with bases 3, 5 and height 5: Area = 0.5 x (3 + 5) x 5 = 20.0
Trapezoid with bases 3, 1 and height 9: Area = 0.5 x (3 + 1) x 9 = 18.0
Rectangle with width 6 and height 3: Area = 6 x 3 = 18</think>
