Length of diagonal of a square is given by following formula
where `a` is the length of the side of the square.
divide both sides by `sqrt2.`
Sides of the room have length of `38/sqrt2` feet.
For this problem, think of the square room as two right triangles. That way, you could use the pythagorean theorem of a^2+b^2=c^2, with c being the length of the diagonal, and a and b the length of the sides.
Since the room is a square, both a and b will be equal, so we can just use the variable x to represent the two sides.
The sides of the room have a length of 26.87 feet.
