Answer 1

Correct Question :-

How many carpets of 3 metre and 2 metre are required to cover a hall of 30 metre by 12 metre.

Answer :-

• Number of carpets are 6 carpets.

Step-by-step explanation:

To Find :-

• Total number of carpets.

★ Solution

Given that,

• Dimension of a carpet = 3m*2m
• Dimension of the room = 30m*12m

∴ The area of carpet and room are :-

» Area of carpet

⇒ Length of carpet × breadth of carpet

⇒ 3m*2m

⇒ 6m²

» Area of room

⇒ Length of room × Breadth of room

⇒ 30m*12m

⇒ 36m²

Now, According the question,

• Number of carpets :-

No. of carpets = Area of room ÷ Area of 1 carpet

⇒ 36m² ÷ 6m²

⇒ 36 ÷ 6

⇒ 6 carpets.

Hence, Total number of carpets are 6 carpets.

Answer 2

Answer:

Given :-

Dimensions of hall = 30 × 12 m

Dimensions of carpet = 3 × 2 m

To Find :-

Total carpet required

Solution :-

We know that

Area of rectangle = Length × Breadth

No. of carpet = Area of hall/Area of one carpet

No. of Carpet = 30 × 12/3 × 2

No. of carpet = 360/6

No. of carpet = 60

Hence,

Number of tiles is 60
