Answer:
length of the carpet = 4m
breadth of the carpet= 2.5m
area of 1 carpet = length of the carpet X breadth of the carpet
= 4 x 2.5 = 10m^{2}
2
length of the hallway = 20m
breadth of the hallway = 13m
Total area of the hall way =length of the hallway x breadth of the hallway
20 x 13 = 260 m^{2}
2
Total number of carpets required to cover completely the floor of hall
=Total area of the hall way/area of 1 carpet
= 260 /10
=26
