Given the following shapes: a trapezoid with bases 9 and 2 and height 3, a rectangle with width 4 and height 5, a rectangle with width 1 and height 5, a right_triangle with base 9 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 9, 2 and height 3: Area = 0.5 x (9 + 2) x 3 = 16.5
Rectangle with width 4 and height 5: Area = 4 x 5 = 20
Rectangle with width 1 and height 5: Area = 1 x 5 = 5
Right triangle with base 9 and height 2: Area = 0.5 x 9 x 2 = 9.0</think>
