Triangle ABC is isosceles with AB = BC. If AB = 20 and [ABC] = 240, then find the perimeter of triangle ABC.
+364 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.
