प्रश्न
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?
उत्तर
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.
