Number of rolls required is 3.

Step-by-step explanation:

  • Step 1: Find the total perimeter of the room given length and breadth.

Perimeter of the room = 2(length + breadth) = 2(12+15) = 2 × 27 = 54 ft

  • Step 2: Find the equivalent measurement in yards of the room since the rolls come in 6 yards.  

Perimeter in yards = 54 × 1/3 = 18 yd

  • Step 3: Find the number of rolls required.

Number of rolls required = 18/6 = 3 rolls
