    130m

    Explanation:

    So your whole area would be 1000m^2

    Long as: 15 + x

    Wide as : x

    We know x (x+15) = 1000

    x^2+15x-1000=0

    Delta: 225+4000=4225

    x=-15+-65/2

    x = 25 and x=-40

    As it is a measurement, we discard the negative measurement.

    Now it is 25m wide and 40 long.

    Multiply by two each to use both sides:

    50+80 = 130m

    Hope you get it!
