Hello!

I found this question that i didn't know the answer to it..The answer book said that the answer is 13cm but without proof..If anyone could tell me the proof that would be great :).

ABCD is an isoscles trapezium in which AD // BC, if BC=2AD=20cm and its area is 180, find the length of each of its legs.

BC=20cm

AD=10cm..
