Best ResponseYou've already chosen the best response.0no it is not. all it gives me is the area which is 36cm2

Best ResponseYou've already chosen the best response.0since 36 is a perfect square.\[ \frac{ 1 }{ 2}(12)(6)=36cm^{2}\]

Best ResponseYou've already chosen the best response.0the base has to be 12

Best ResponseYou've already chosen the best response.2No. \[(0.5)(24)(3)=36\]

Best ResponseYou've already chosen the best response.0so your saying 24 would be the length of leg xy?

Best ResponseYou've already chosen the best response.1@winterfez, that's incorrect, since 72 = 36x2 = 9x8= 18x4 and so on.. , many possibilities , i think phoenixfire leads him on the right track, need more info on this to solve.

Best ResponseYou've already chosen the best response.0well for this question you need to know either the height or the base

Best ResponseYou've already chosen the best response.2Could be a lot of different numbers. You're missing information.

Best ResponseYou've already chosen the best response.0i can take a picture of the diagram on my cell and upload it for you guys to see the diagram given to me

Best ResponseYou've already chosen the best response.0\[\frac{ 1 }{ 2}bh=36cm ^{2}\] I don't think you can find from this equation. Like PhoenixFire point out you need to know 1 more information for either base or height

Best ResponseYou've already chosen the best response.2Leg XY is twice as long as YZ. That's the info we needed. Let b=XY and h=2b \[A={1 \over 2}2b^2=b^2\]\[\sqrt{36}=b=6\] Your leg XY=6 and YZ=12

Best ResponseYou've already chosen the best response.1phoenixfire, you got the other way around :) XY is twice as long as YZ :)

Best ResponseYou've already chosen the best response.0sorry bout that. my bad. this is my first time using this site. i thought i mentioned it. but thank you very much PhoenixFire, tamotan, and winterfez.

Best ResponseYou've already chosen the best response.0so the length of leg xy is 24?

PhoenixFire

Best ResponseYou've already chosen the best response.2I see. b=2h h=YZ \[A={1 \over 2}2h^2=h^2\]\[h=\sqrt{36}=6\] \[b=2h=2(6)=12\] XY = 12
