Given the following shapes: a right_triangle with base 7 and height 9, a trapezoid with bases 5 and 4 and height 4, a square with side 1, a right_triangle with base 1 and height 4, a rectangle with width 8 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 7 and height 9: Area = 0.5 x 7 x 9 = 31.5
Trapezoid with bases 5, 4 and height 4: Area = 0.5 x (5 + 4) x 4 = 18.0
Square with side 1: Area = 1^2 = 1
Right triangle with base 1 and height 4: Area = 0.5 x 1 x 4 = 2.0
Rectangle with width 8 and height 4: Area = 8 x 4 = 32</think>
