    Answer:

    the length of the third side is 12.1m

    Step-by-step explanation:

    by Pythagoras we know the relationship of the sides of a rectangular triangle that is given by the formula h^2 = l1^2 + l2^2

    h = hypotenuse = 14m

    l1 = leg1 = 7m

    l2 = leg2

    h^2 = l1^2 + l2^2

    14^2 = 7^2 + l2^2

    196 = 49 + l2^2

    196 – 49 = l2^2

    147 = l2^2

    √147 = l2

    12.124 = l2

    rounding to the nearest tenth

    l2 = 12.1
