Best ResponseYou've already chosen the best response.0i got the area form each triangle sepreatly then added them up and got 128.77

Best ResponseYou've already chosen the best response.0That should be right. You have two sides, you can calculate the third.

Best ResponseYou've already chosen the best response.1you got that for the bigger one? because I got 21.81. hmm how did you get that?

Best ResponseYou've already chosen the best response.0i multiply 7.9 and 23.2 for the big one then divide by 2 same for the small one 9.4x7.9 then divide by 2

Best ResponseYou've already chosen the best response.1hmm that might be why. i used a^2+b^2=c^2 to get the base of both triangles first. to get the area you do bh/2. base is the bottom measurement.

Best ResponseYou've already chosen the best response.0well i have to find the area so i found he area of both then add them together i think thats how?

Best ResponseYou've already chosen the best response.1yes but you're finding the area the wrong way. first you have to find the base. without the base measurement you can't find area. once you do it that way, you can add them

Best ResponseYou've already chosen the best response.0poo so how can i find the base? can you help me plz :)

Best ResponseYou've already chosen the best response.1okayy. a triangle is sides a, b and c. now the slanted side is always c. For the smaller one the sides are b=7.9 and c=9.4. plug it into this and solve. a^2+b^2=c^2 let me know what you get.

Best ResponseYou've already chosen the best response.0so it would be 62.41 and 88.36 then subtract = 25.9 right?

Best ResponseYou've already chosen the best response.1yes! now find the square root since that is squared right now.

Best ResponseYou've already chosen the best response.1exactly :) now do the same for the bigger triangle.

Best ResponseYou've already chosen the best response.0i got square root of 21.81?

Best ResponseYou've already chosen the best response.1oh wait, no i'm sorry. now with each of the bases you do bh/2 to get the area. my bad. So it'll be 5.09*7.9 and 21.81*7.9
