Given:
Length = 24 m
Breath = 18 m
Thus, we have:
Area of the rectangular hall = 24 18
= 432 m2
Length of each carpet = 2.5m
Breath of each carpet = 80cm = 0.80 m
Area of one carpet = 2.5 x 0.8 = 2 m2
Number of carpets required = \(\frac{Area\,of\,the\,hall}{Area\,of\,the\,carpet}\)
= \(\frac{432}{2}=216\)
Therefore, 216 carpets will be required to cover the floor of the hall.
