Answer:
A = 811.84 centimeters squared
Explanation:
I cut the shape in half (two trapezoids)
I did the area for one trapezoid:
A = 22.3+46.5/2 (11.8)
A = 68.8/2 (11.8)
A = 34.4 (11.8)
A = 405.92 centimeters squared
Since this is only half of the shape, I multiplied the area by 2.
A = 405.92 (2)
A = 811.84 centimeters squared
