The length of the base of a isosceles triangle is one forth the length of one of its legs. If the premimeter of the triangle is 16 inches, what is the length of the base.

  • algebra 1 -

    let the base be x
    then each of the other 2 equal legs would be 4x

    4x + 4x + x = 16
    9x = 16
    x = 16/9 inches
