Given the following shapes: a square with side 1, a square with side 4, a rectangle with width 5 and height 2, a trapezoid with bases 7 and 5 and height 3, a right_triangle with base 2 and height 3. 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
Square with side 4: Area = 4^2 = 16
Rectangle with width 5 and height 2: Area = 5 x 2 = 10
Trapezoid with bases 7, 5 and height 3: Area = 0.5 x (7 + 5) x 3 = 18.0
Right triangle with base 2 and height 3: Area = 0.5 x 2 x 3 = 3.0</think>
