The answer is, "C. 181.5 in²."
The formula to calculate the area of a trapezoid is h.
The bottom and top bases must be divided by 2.
Divide that sum by 2, then multiply the height.
16.5·11=181.5
The area of the trapezoid is 181.5 in².
Your answer: C) 181.5 Inches Squared
The way to find the area of this figure is to do Base Plus Base Times Height Divided By 2
Base Plus Base = 21.5 + 11.5 = 33
33 Times 11 = 363
363 Divided By 2 = 181.5
Best Of Luck,
