Step-by-step explanation:

length=540cm

breadth=480cm

as the length is shorten from two sides

so 2*40=80

540-80=460

480-80=400

length and breadth of carpet=460 and 400

area=460*400

184000cm

1840m

Step-by-step explanation:

Area of floor =l×b

=[5.4×4.8]m

=25.92m2

Area of carpet = (side)2

= (40)2 cm

=1600 cm2

Converting 25.92 into cm2

= 2592 cm2

Area of floor = (2592-1600) cm2

= 992cm2

converting area of floor into m2

= 992/100 = 9.92m2
