    x^2 is only the measure of 2 sides?

    to find the length of the diagonal of a square, multiply the length of one side by the square root of 2. |dw:1433488980540:dw|

    you find the side by using the equation side = \[\sqrt{200}\]

    Area of the square = side^2 i.e. 200 = side^2 side = \[\sqrt{200}\] \[=10\sqrt{2}\] m diagonal of a square \[=\sqrt{2} side \]\[=10\sqrt{2}\times \sqrt{2}=20 m\]

    Hence diagonal of the square is 20 metres.

    200=s^2 s=10√2 *pythagorean d^2=2(10√2)^2 d^2=2(200) d^2=400 d=20
