The formula for the area of a trapezoid is A = (1/2)(b1 + b2)(h), where b1 and b2 are the lengths of the two bases, and h is the height.
Calculating for the area of the isosceles trapezoid given the values:
A = (1/2)(22 + 9)(5)
A = (1/2)(31)(5)
A = 15.5 * 5
A = 77.5
Therefore, the area of the isosceles trapezoid is 77.5.
The correct answer is B) 77.5.
