Given the following shapes: a right_triangle with base 2 and height 1, a right_triangle with base 6 and height 4, a rectangle with width 6 and height 7, a square with side 1, a square with side 7, a rectangle with width 7 and height 6. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Right triangle with base 2 and height 1: Area = 0.5 x 2 x 1 = 1.0
Right triangle with base 6 and height 4: Area = 0.5 x 6 x 4 = 12.0
Rectangle with width 6 and height 7: Area = 6 x 7 = 42
Square with side 1: Area = 1^2 = 1
Square with side 7: Area = 7^2 = 49
Rectangle with width 7 and height 6: Area = 7 x 6 = 42</think>
