Let's assume that the length of the red ribbon is x meters. According to the given information, the white ribbon is 3 meters longer than the red ribbon.

Therefore, the length of the white ribbon can be calculated as x + 3 meters.

So, the mother bought x + 3 meters of white ribbon.

Calculation of Fabric for Curtains
