Given the following shapes: a rectangle with width 5 and height 4, a right_triangle with base 8 and height 1, a right_triangle with base 4 and height 2, a right_triangle with base 6 and height 4, a right_triangle with base 4 and height 3. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Rectangle with width 5 and height 4: Area = 5 x 4 = 20
Right triangle with base 8 and height 1: Area = 0.5 x 8 x 1 = 4.0
Right triangle with base 4 and height 2: Area = 0.5 x 4 x 2 = 4.0
Right triangle with base 6 and height 4: Area = 0.5 x 6 x 4 = 12.0
Right triangle with base 4 and height 3: Area = 0.5 x 4 x 3 = 6.0</think>
