Given the following shapes: a rectangle with width 4 and height 7, a trapezoid with bases 3 and 6 and height 1, a right_triangle with base 1 and height 6, a trapezoid with bases 7 and 5 and height 1, a right_triangle with base 7 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>Rectangle with width 4 and height 7: Area = 4 x 7 = 28
Trapezoid with bases 3, 6 and height 1: Area = 0.5 x (3 + 6) x 1 = 4.5
Right triangle with base 1 and height 6: Area = 0.5 x 1 x 6 = 3.0
Trapezoid with bases 7, 5 and height 1: Area = 0.5 x (7 + 5) x 1 = 6.0
Right triangle with base 7 and height 6: Area = 0.5 x 7 x 6 = 21.0
Square with side 4: Area = 4^2 = 16</think>
