Take to consider in finding the Area of a Trapeziod:
A=(1/2)(h)(b1+b2)
Substitute givensystem%28A=144sqin%2Ch=12in%29
144in%5E2=%281%2F2%29%2812%29%28b%5B1%5D%2Bb%5B2%5D%29--->
12=%28b%5B1%5D%2Bb%5B2%5D%29%2F2---->*Take note: Length of the Median is the Average length of the bases, given by formula==>(b1+b2)/2. See below:
---> Therefore, Median=(b1+b2)/2=12inches Answer
