Question 1064221
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.
{{{(x+8)^2 = x^2 + (x+7)^2}}}
-------
If x is in cms as stated, not meters:
{{{(x+8)^2 = (0.01x)^2 + (x+7)^2}}}
