Best ResponseYou've already chosen the best response.0Ah ok. So lets use co ordinate geometry . Can you tell me equation of line passing through (1/2,2) and (3,2)?

Best ResponseYou've already chosen the best response.0of course it does(but thats irrevelant to finding area of a triangle. :P)

Best ResponseYou've already chosen the best response.0Ok I'll assume you did that correctly. Now find distance of (2,3) from this line.

Best ResponseYou've already chosen the best response.0Ok Suppose i have a line ax+by+c=0. And a point h,k. Then disatnce of point from this line would be (ah+bk+c)/sqrt(a^2+b^2). If you get negative value just make it positive by removing minus sign.

Best ResponseYou've already chosen the best response.0You did not understand the formula? Damn. Ok In your case the line is 7y+8x+10=0. And the point is 2,3. Si a=7,b=8,c=10. h=2,k=3. Using the formula you get (7*2+8*3+10)/sqrt(64+49)=48/sqrt(113).
