Given the following shapes: a trapezoid with bases 5 and 4 and height 1, a square with side 2, a rectangle with width 1 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 5, 4 and height 1: Area = 0.5 x (5 + 4) x 1 = 4.5
Square with side 2: Area = 2^2 = 4
Rectangle with width 1 and height 4: Area = 1 x 4 = 4</think>
