Given the following shapes: a square with side 1, a trapezoid with bases 2 and 4 and height 7, a rectangle with width 7 and height 3, a right_triangle with base 5 and height 4. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Square with side 1: Area = 1^2 = 1
Trapezoid with bases 2, 4 and height 7: Area = 0.5 x (2 + 4) x 7 = 21.0
Rectangle with width 7 and height 3: Area = 7 x 3 = 21
Right triangle with base 5 and height 4: Area = 0.5 x 5 x 4 = 10.0</think>
