Concept :

An issue can be tackled utilizing the unitary strategy by first deciding the effect of a specific unit, and afterward increasing that worth to decide the expected worth. A solitary unit's worth not entirely settled from the upsides of various units, and different units' qualities still up in the air from the upsides of single units utilizing the unitary procedure. We commonly use this method for math computations. The unitary methodology is utilized when we have a few things with a worth that we really want to work out the worth of every unit by essentially partitioning the complete worth by the quantity of units.

The length of a cloth is $15/2 m.$

The cost of this cloth at ₹ $36$ whole $2/5 per m$.​
