Given the following shapes: a rectangle with width 4 and height 7, a trapezoid with bases 2 and 1 and height 3, a square with side 1, a square with side 2, a right_triangle with base 1 and height 1, a square with side 2. 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 2, 1 and height 3: Area = 0.5 x (2 + 1) x 3 = 4.5
Square with side 1: Area = 1^2 = 1
Square with side 2: Area = 2^2 = 4
Right triangle with base 1 and height 1: Area = 0.5 x 1 x 1 = 0.5
Square with side 2: Area = 2^2 = 4</think>
