Step-by-step explanation:
You could calculate the area of the trapezoid and then subtract the area of the triangle.
Area of a trapezoid:
Plug values in:
Add 6 and 12:
Simplify:
Area of a triangle:
Plug values in:
Simplify:
A = 36
Subtract the area of the triangle from the area of the trapezoid
54 - 36 = 18
You could also calculate the area of the shaded region by assuming that they're congruent meaning the base would be half of 6 which is 3 and the height would be 6 so the area of one would be 1/2 (6)(3) but since they're is 2 you wouldn't need the 1/2 since multiplying by 2 would cancel it out so the area would be (6)(3) = 18
