Given the following shapes: a right_triangle with base 5 and height 2, a rectangle with width 7 and height 3, a right_triangle with base 4 and height 7, a trapezoid with bases 7 and 7 and height 2. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 5 and height 2: Area = 0.5 x 5 x 2 = 5.0
Rectangle with width 7 and height 3: Area = 7 x 3 = 21
Right triangle with base 4 and height 7: Area = 0.5 x 4 x 7 = 14.0
Trapezoid with bases 7, 7 and height 2: Area = 0.5 x (7 + 7) x 2 = 14.0</think>
