Question

how many carpets ,each 4 m long and 2.5 m wide, will be required to cover comletely the floor of hall 20 m long 13m wide.​

Answer 1

Answer:

Step-by-step explanation:

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$^{2}$

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$^{2}$

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

Answer 2

Answer:

26 carpets were needed to cmpletely cover the floor.

Step-by-step explanation:

1. area of carpet = L x B

                           =  (4 x 2.5)m

                           = 10.0 m

2. area of the floor =  L x B

                               =  (20 x 13)m

                               = 260 m

Therefore, the carpets needed to cover the floor = area of floor / area of carpet

                                                                                   =  260/10

                                                                                    = 26 m.
