sides of triangle measure: x, 4x-2 and 4x-2 since isosceles means both legs are equal

perimeter is the sum of all sides, so set up equation:

104 = 4x - 2 + 4x - 2 + x

104 = 8x - 4 + x

104 = 9x - 4

108 = 9x

x = 108/9

x = 12

perimeter is the sum of all sides, so set up equation:

104 = 4x - 2 + 4x - 2 + x

104 = 8x - 4 + x

104 = 9x - 4

108 = 9x

x = 108/9

x = 12
