The floor of a rectangular hall is 24 m long and 18 m wide. How many carpets, each of length 2.5 m and breath 80 cm, will be required to cover the floor of the hall?

Given: Length of carpet = 2.5 m


Breadth of carpet = 80 cm = 0.8 m


Length of hall = 24 m


Breadth of hall = 18 m



We know that,


Area of hall = Length × Breadth


= 24 m × 18 m


= 432 m2


And,


Area of carpet = Length × Breadth


= 2.5 m × 0.8 m


= 2 m2


Now,




= 216 carpets
