The complete question is as follows.
The equation a = can be used to determine the area , <em>a</em>, of a trapezoid with height , h, and base lengths, and . Which are equivalent equations?
(a)
(b)
(c) =
(d)
(e) = h
Answer: (a) ; (d) ;
Step-by-step explanation: To determine :
a =
2a = ()h
To determine h:
a =
2a =
= h
To determine
a =
2a =
Checking the alternatives, you have that and = h, so alternatives <u>A</u> and <u>D</u> are correct.
