    Finding sides of a Triangle

    Please help

    I don't understand this question, it isn't making any sense to me

    The short side of an isosceles triangle is one half the length of the equal sides, If the perimeter is 8.5cm, what are the lengths of the three sides of the triangle?

    Thank you

    did you make a sketch ?

    let the longer sides = 2x each

    short side = x

    x + 2x + 2x = 8.5

    Yes i made a sketch, i was looking at the one-half and putting it down as a fraction. They make these problems so confusing.
