Answer:
A = 66.7 in²
Step-by-step explanation:
The shaded sections of the trapezoid are right triangles.
Therefore the area of the shaded sections = the area of the two triangles
Area of a triangle = ½*bh
✔️Area of the first triangle with the following dimensions:
b = 8 in
h = 9.2 in
Area = ½*8*9.2 = 4*9.2 = 36.8 in²
✔️Area of the second triangle with the following dimensions:
b = 6.5 in
h = 9.2 in
Area = ½*6.5*9.2
= 29.9 in²
✔️Area of the shaded sections = 36.8 + 29.9 = 66.7 in²
