Question

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

Answer 1

Given: Length = 24 m 

Breath = 18 m

Thus, we have:

Area of the rectangular hall=`24xx18` 

=` 432m^2` 

Length of each carpet `2.5m`

Breath of each carpet `80cm=0.80 m` 

Area of one carpe=`2.5xx0.8=2 m^2` 

Number of carpets required= `"Area of the hall"/"Area of  the carpet"=432/2=216` 

Therefore, 216 carpets will be required to cover the floor of the hall.
