Question

find the cost of carpeting a room 13m by 9 metre with a carpet of width 75cm at the rate of rupees 105 per metre​

Answer 1

Answer:

Step-by-step explanation:

1m = 100cm

Given - length of room = 13m

Breadth = 9m

Area of rectangle = l x b

= 13 x 9

= 117

Therefore area of the room is 117sq.m ( 11700sq.cm)

Side of carpet = 75 cm

Area of the carpet = 75 x 75

= 5625

Therefore area of carpet is 5625sq.cm (56.25sq.m)

Cost of 1sq. M = 105

Cost of 56.25sq.m = 5906.25

Therefore the cost will 5906.25 approx. 5905

Answer 2

Answer

Rs16380

Step by step explanation

Let length of the carpet be L

Width = 75cm or 0.75m

Area to be covered by the carpet=117m^2

Area=length×breadth

Area=length×breadth117 =L×0.75

Area=length×breadth117 =L×0.75L=11700/75

Area=length×breadth117 =L×0.75L=11700/75=156m

Rate of carpeting=Rs 105 per meter.

=Rs(105×156)

=Rs(105×156)=Rs16380

Ans.=Rs16380
