A rectangular room is 10 m long and 7.5 m wide. Find the costfloor with carpet 1.25 m wide at250 per metre.

Answer»

Length of the room= 10 m

Width of the room=7.5 m

Area of the floor= 10*7.5 = 75 m2

Width of the carpet=1.25 m

Now, area of the carpet= area of the floor

So, length of carpet = 75/1.25

= 60m

Hence, cost of covering the foor

= Rs 250*60

= Rs15000
