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.

a^2+b^2=c^2

a^2+b^2=38^2

a^2+b^2=1444

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.

x^2+x^2=1444

2(x^2)=1444

x^2=722

x=26.87

The sides of the room have a length of 26.87 feet.
