Given the following shapes: a trapezoid with bases 2 and 1 and height 4, a rectangle with width 1 and height 9, a square with side 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 2, 1 and height 4: Area = 0.5 x (2 + 1) x 4 = 6.0
Rectangle with width 1 and height 9: Area = 1 x 9 = 9
Square with side 4: Area = 4^2 = 16</think>
