do you know the formula for the area of a trapezoid?

a quick search in google gives this picture https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=area+of+a+trapezoid

anonymous · Answer

judging from that picture, can you solve your question?

rayman5766 · Answer

ok hold on

anonymous · Answer

@Agl202 that is incorrect

anonymous · Answer

@Agl202 you are not taking in to account the fact that in a trapezoid, the base length on the top and bottom varies

rayman5766 · Answer

well I am stuck A 8 and B would be 10 right

anonymous · Answer

Yep. A and B are the side lengths.

So if the equation is Area = [(a+b)/2] * h

anonymous · Answer

then plug in A and B. What is (a+b) / 2 in this case?

anonymous · Answer

in other words, you already know the area and side lengths. so you could say

Area = [(a+b)/2] * h
or
108 = (10+8)/2 * h

anonymous · Answer

you should be able to solve for h, which is what you want to know (the height)
