hey guys

the problem is the legs of a triangle are x and y. find the equation that will maximize the area of the triangle given that 2x+y=18

is the answer 40.5 cubic units

thanks alot

I'm not sure what you are asking here. A general triangle does not

**have**"legs". Is this a right triangle with legs x and y? In that case, the area is given by A= xy/2. If you are also required that 2x+y= 18 so that y= 18- 2x so the area is given by A= x(18- 2x)/2= 9x- x^2. That's a parabola and you can find a maximum value by completing the square. - Jan 1st 2013, 01:24 PMubhuttoRe: optimization problem - need confirmation
i was trying to help someone but thats all the question says, i calculated it like an isosceles triangle but thanks alot for looking into the question
