Question

A room is 16m long and 13.5m broad .find the cost of covering its floor with 75m wide carpet at Rs60 per metre?

Answer 1

$\large{\boxed{\bold{Answer:}}}$

Length - 16m

Breadth - 13.5m

So, the area of Room = 16 × 13.5

Now,

Breadth of the carpet = 75 cm = 0.75m

$Length\:of\:carpet\:required\:to\:cover\:the\:room \\ \\ = \frac{16 \times 13.5}{0.75} = 288m \\ \\ Cost = 288 \times 15 = 4320rs$

Thus, the cost of covering the floor is 4320 Rupees.

$\large{\boxed{\bold{Hope\:it\:helps\:you!}}}$

Answer 2

area of room = length * breadth=16*13.5 m sq.

width of carpet=0.75 m

length of carpet required = 16*13.5/0.75=288 m

cost= 15 *288=4320 rupees
