Question

Answer the quetions please look below

Answer 1

38 in^2 and 26 in^2

Explanation:

1. The formula of the area of a trapezoid is
`A = (1)/(2) (b_(1) + b_(2))h` where b = base and h = height.

So,
`A = (1)/(2) (7+12)(4)` = 38
`in^(2)`

2.
`A = (1)/(2)(5+8)(4)` = 26
`in^(2)`

No, Betsy is not correct. She likely forgot to multiply by 1/2 when calculating the area. The correct answer is 26 inches squared.
