A rhombus has one side measuring 6 m. What are the lengths of the other 3 sides?

A rhombus is defined as a type of polygon that is a quadrilateral with all four sides of equal length. Because of this defining property, if one side of a rhombus is known to measure 6 meters, it follows that all four sides must also measure 6 meters.

This understanding clarifies why the correct answer is that the lengths of the other three sides are also 6 meters. In a rhombus, the sides are congruent, meaning they have the same length. Hence, knowing just one side provides sufficient information to determine the lengths of the other sides, reinforcing the property of the shape itself.

The other choices present lengths that either violate this property of congruence or suggest configurations that do not reflect the characteristics of a rhombus.
