2 similar trapizoids LMCD and ABLM using the ratios of corresponding sides $\frac{LM}{DC} = \frac{AB}{LM}$ or $\frac{LM}{125} = \frac{46}{LM}$ just cross multiply and solve

thats all you do?

5. anonymous

wait im kinda confused...can you do it step by step?

6. campbell_st

this is the way they look |dw:1356036555596:dw| the trapizoids are similar so match the corresponding sides when you get the ratio shown, just cross multiply $LM^2 = 125 \times 46$ and then solve

if you do it the way this person does it... the answer would be 75.83 approx.

8. anonymous

is there a different way to do this?

i think. and sorry for the late reply
