The sides of a rectangular floor are xcm and (x+7)m. The diagonal is (x+8)m. Calculate in meters the dimension of the floor.
-----------
It's a right triangle.
x+8 is the hypotenuse.
%28x%2B8%29%5E2+=+x%5E2+%2B+%28x%2B7%29%5E2
-------
If x is in cms as stated, not meters:
%28x%2B8%29%5E2+=+%280.01x%29%5E2+%2B+%28x%2B7%29%5E2
