Given the following shapes: a right_triangle with base 4 and height 7, a square with side 4, a right_triangle with base 6 and height 7, a rectangle with width 3 and height 1. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 4 and height 7: Area = 0.5 x 4 x 7 = 14.0
Square with side 4: Area = 4^2 = 16
Right triangle with base 6 and height 7: Area = 0.5 x 6 x 7 = 21.0
Rectangle with width 3 and height 1: Area = 3 x 1 = 3</think>
