The lengths of the sides of isosceles triangle ABC are 3x + 62, 7x + 30, and 5x + 60 feet. What is the least possible number of feet in the perimeter of ABC?

Isoc triangle so two of the sides are equal     either  

  3x+62 = 5x+60         then x = 1

or

   3x+62= 7x + 30       then x = 8

or

   7x+30 = 5x + 60      then x = 15        the value of 'x' which will produce the smallest perimeter is  x = 1       You can finish......
