In a right triangle, the diagonal is the hypotenuse, found with the Pythagorean theorem. Square each side: 4 ft becomes 16, and 6 ft becomes 36. Add them to get 52. The hypotenuse is the square root of 52, which is about 7.211, so the length is approximately 7.2 ft. Among the options, 7.2 ft matches this calculation. The other numbers would imply a different sum of squares and aren’t close to sqrt(52).
