0.5(27)(8)
13.5(8)
108
Therefore, our area is D) 108 cm².
I hope this helps!
Find the Area of the Trapezoid: A (Base 1 ==> 12, Base of Base 2 ==> 15, Height ==> 8
Formula: ==> A = 1 / 2 ( b1 + b2 ) * h
Area of Base 1: ====> 12
Base of Base 2: ===> 15
Height: ====> 8
Area of Base 1: ====> 12
Base of Base 2: ===> 15
Height: ====> 8
Solve For Area:
A = a + b / 2 * h
A = 12 + 15 / 2 * 8
A ==> 108 cm^2
Answer: Letter Choice, (D), 108 cm^2
Hope that helps!!! : )
