an isosceles triangle is one in which two sides are the same length. The perimeter of an isosceles triangle is 36cm if the length of the congruent sides is 4 times the length of the third side, find the dimentions of the triangle

Answer 1

if b is base
8 b + b = 36
9 b = 36
b = 4
then 4 b = 16
so 16 , 16 and 4
