Triangle ABC is isosceles with AB = BC. If AB = 20 and [ABC] = 240, then find the perimeter of triangle ABC.

i don't think it is possible

imagine 20x/2=240

x=24

but according to the pythagorean theorem, 20^2=24^2+something squared

you can tell something is wrong

i may be wrong, because i am assuming you mean that the area of abc=240

but if the perimeter of abc is 240, thats alos not possible because two sides of a triangle always has to be greater than the other one.
