1.	A room is 16 m long and 13.5 m broad. Find the cost of covering its floor with 75-m-wide carpet at ₹ 60 per metre.
Answer» As, the area of the floor = length x breadth = 16 x 13.5 = 216 m² And, the width of the carpet = 75 m So, the length of the carpet required = \(\frac{Area\,of\,the\,floor}{Width\,of\,the\,carpet}\) = \(\frac{216}{75}\) = 2.88 m Now, the cost of the carpet required = 2.88 x 60 = 172.80 Hence, the cost of covering the floor with carpet is 172.80.

A room is 16 m long and 13.5 m broad. Find the cost of covering its floor with 75-m-wide carpet at ₹ 60 per metre.

Answer»

As, the area of the floor = length x breadth

= 16 x 13.5

= 216 m²

And, the width of the carpet = 75 m

So, the length of the carpet required = \(\frac{Area\,of\,the\,floor}{Width\,of\,the\,carpet}\)

= \(\frac{216}{75}\)

= 2.88 m

Now, the cost of the carpet required = 2.88 x 60 = 172.80

Hence, the cost of covering the floor with carpet is 172.80.
