The area of the floor of a rectangular hall of length 60m is 1200m2. Carpets of size 8m × 6m are available. How many carpets are required to cover the hall?
25
First, we need to calculate the area of one carpet:
Area of one carpet = 8 × 6 = 48m2.
Since total area of the floor of the hall = 1200m2.
Therefore,number of carpets required = area of floorarea of one carpet = 120048 = 25.
Hence the correct answer is option B.
