Given the following shapes: a trapezoid with bases 1 and 2 and height 3, a square with side 4, a square with side 9, a square with side 7. What is the total area of all shapes? Please round the result to the nearest integer.
<think>Trapezoid with bases 1, 2 and height 3: Area = 0.5 x (1 + 2) x 3 = 4.5
Square with side 4: Area = 4^2 = 16
Square with side 9: Area = 9^2 = 81
Square with side 7: Area = 7^2 = 49</think>
