Question

8. A corridor measures 150 m x 5 m. It is to
be covered by a carpet of width 2.5 m. If the
carpet is priced at 20 per metre, then find
the total cost of the carpet required to cover
the whole corridor.​

Answer 1

Step-by-step explanation:

Total area of corridor = 150 x 5

total length of cloth required = 2 x 150 m = 300 m

total cost to cover the whole corridor = 300 x 20 = ₹ 6000 /-

Answer 2

Area of corridor= 150m×5

= 750m²

Area of carpet = l×2.5

750 = l×2.5

$l = \frac{750}{2.5} \\ l = 300m$

cost = 300×20

= ₹6000
