Given the following shapes: a square with side 4, a trapezoid with bases 4 and 6 and height 1, a rectangle with width 6 and height 4, a rectangle with width 3 and height 3, 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 4, 6 and height 1: Area = 0.5 x (4 + 6) x 1 = 5.0
Rectangle with width 6 and height 4: Area = 6 x 4 = 24
Rectangle with width 3 and height 3: Area = 3 x 3 = 9
Rectangle with width 6 and height 3: Area = 6 x 3 = 18</think>
