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.
