    Let the width be x ft

    the length will be (x+14) ft

    hypotenuse is 34 ft

    given that our triangle is right triangle, using Pythagorean theorem?

    c^2=a^2+b^2

    substituting our values in the formula we get:

    34^2=x^2 + (x+14) ^2

    1,156=x^2+x^2+28x+196

    simplifying this we get

    0=2x^2+28x-960

    solving the quadratic equation we get:

    x=16 or x=-30

    therefore the width is 16 ft and the length is 16+14=30
