17m
Explanation:
Draw a picture for the situation:
__________15m___________

b | | 8m

a
We can assume the floor is a rectangle. Cut the triangle diagonally in half.
The rectangles has all right angles and is composed of two right triangles.
Use the Pythagorean formula and solve for the length of the hypotenuse to find the distance between two the opposite corners. I labelled two of the sides a and b.
The formula is: a² + b² = c² , where c is the distance. Substitute the side lengths a and b and solve for c.
a² + b² = c²
15² + 8² = c²
Simplify:
225 + 64 = c²
c² = 289
c = √289
c = 17
The distance between two opposite corners on the floor is 17 metres.
