Question 419652: The perimeter of an isosceles triangle is 35 cm. If the length of each of the congruent sides is 3 times the length of the third side, find the dimensions of the triangle.
So far I've got:
a + b + c = 35
3b = a
3b = c
I'm not sure if that's even right, though.
Thank you.

You have to continue:
3b+3b+b=35
7b=35
b=35/7
b=5
a=c=3*5=15
