the diagonal forms the hypotenuse with the two sides
x^2 = 30^2 _40^2
x^2= 900 +1600
x^2= 2500
x= sqrt 2500
= 25m

        Calculations in the post by @mananth are incorrect.
        I came to provide a correct solution.


the diagonal forms the hypotenuse with the two sides
x^2 = 30^2 + 40^2
x^2 = 900 +1600
x^2 = 2500
x = sqrt(2500)
= 50 meters.
