Question

How many meters are carpet , 75 cm wide will be required to cover the floor of a room which is 20 m long and 12 m broad ?

Answer 1

Area of the room = 20 x 12 = 240m²

width of the carpet = 0.75 m

Length of carpet needed = 240 ÷ 0.75 = 320m

Answer 2

Answer:

length of floor of the room = 20 m

breadth of floor of the room=12 m

Area of room = l×b

= 20×12

= 240 m²

width of carpet = 75 cm

Conversion: 1m = 100 cm

75 cm = 75

100

=0.75 m

240÷0.75= 320 m

Thus, 320 m carpet is required.
