Given the following shapes: a trapezoid with bases 3 and 5 and height 1, a trapezoid with bases 9 and 7 and height 3, a right_triangle with base 9 and height 9, a right_triangle with base 4 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 3, 5 and height 1: Area = 0.5 x (3 + 5) x 1 = 4.0
Trapezoid with bases 9, 7 and height 3: Area = 0.5 x (9 + 7) x 3 = 24.0
Right triangle with base 9 and height 9: Area = 0.5 x 9 x 9 = 40.5
Right triangle with base 4 and height 2: Area = 0.5 x 4 x 2 = 4.0</think>
