Given the following shapes: a trapezoid with bases 4 and 5 and height 8, a right_triangle with base 3 and height 2, a right_triangle with base 8 and height 5, 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 4, 5 and height 8: Area = 0.5 x (4 + 5) x 8 = 36.0
Right triangle with base 3 and height 2: Area = 0.5 x 3 x 2 = 3.0
Right triangle with base 8 and height 5: Area = 0.5 x 8 x 5 = 20.0
Square with side 4: Area = 4^2 = 16</think>
