Given the following shapes: a trapezoid with bases 8 and 4 and height 1, a trapezoid with bases 7 and 3 and height 3, a right_triangle with base 3 and height 4, a rectangle with width 5 and height 6, 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 8, 4 and height 1: Area = 0.5 x (8 + 4) x 1 = 6.0
Trapezoid with bases 7, 3 and height 3: Area = 0.5 x (7 + 3) x 3 = 15.0
Right triangle with base 3 and height 4: Area = 0.5 x 3 x 4 = 6.0
Rectangle with width 5 and height 6: Area = 5 x 6 = 30
Square with side 4: Area = 4^2 = 16</think>
