ANSWER
A. 70 in^2
EXPLANATION
The area of a tra-pezoid is
[tex] = \frac{1}{2} (sum \: of \: parallel \: sides) \times height[/tex]
Substitute the side lengths into the formula to obtain,
[tex] = \frac{1}{2} (8 + 14) \times 7[/tex]
Simplify the parenthesis
[tex] = \frac{1}{2} (20) \times 7[/tex]
Cancel out the common factors,
=10×7
Simplify
[tex] = 70 {in}^{2} [/tex]
The correct answer is A
