Given the following shapes: a square with side 1, a trapezoid with bases 4 and 3 and height 4, a right_triangle with base 2 and height 1, a trapezoid with bases 1 and 2 and height 1. 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 4, 3 and height 4: Area = 0.5 x (4 + 3) x 4 = 14.0
Right triangle with base 2 and height 1: Area = 0.5 x 2 x 1 = 1.0
Trapezoid with bases 1, 2 and height 1: Area = 0.5 x (1 + 2) x 1 = 1.5</think>
