Given the following shapes: a rectangle with width 7 and height 3, a right_triangle with base 5 and height 1, a rectangle with width 2 and height 6, a trapezoid with bases 3 and 1 and height 7, a square with side 4, a right_triangle with base 5 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 7 and height 3: Area = 7 x 3 = 21
Right triangle with base 5 and height 1: Area = 0.5 x 5 x 1 = 2.5
Rectangle with width 2 and height 6: Area = 2 x 6 = 12
Trapezoid with bases 3, 1 and height 7: Area = 0.5 x (3 + 1) x 7 = 14.0
Square with side 4: Area = 4^2 = 16
Right triangle with base 5 and height 3: Area = 0.5 x 5 x 3 = 7.5</think>
