PLEASE HELP I REALLY AM BAD AT MATH. I JUST NEED THIS. NO ONE HAS ANSWERED MY PAST QUESTIONS WHILE I ANSWER THERES ;( 4ABC is isosceles with AB = AC. All three side lengths of 4ABC and also
altitude AD are positive integers.
If the area of 4ABC is 60 cm2
, determine all possible perimeters of 4ABC.
Note: You may use the fact that the altitude of an isosceles triangle drawn to
the unequal side bisects the unequal side.

Thank you for ignoring this friendly request of help :(
BTW U GET 20 POINTS IF U ANSWER ME
