Answer 2

Given:-

• A carpet is 30 m 75 cm long and 80 cm wide.

⠀

To find:-

• It's cost at Rs.20 per square meter.

⠀

Solution:-

Here,

• Length (l) = 30m 75cm = 3075 cm
• Breadth (b) = 80 cm

⠀

According to the question,

Firstly,

• Finding the area of a carpet.

⠀

We know that,

→ Area of rectangle = length × breadth

⇛ A = l × b

⇛ A = 3075 × 80

⇛ A = 30750 × 8

⇛ A = 246000 cm²

⇛ A = 2460 m²

⠀

Now,

• Finding the cost of carpet at Rs.20.

⠀

⇛ Area of a carpet × 20

⇛ 2460 × 20

⇛ Rs.49200

⠀

Hence,

• the cost of a carpet at Rs.20 is Rs.49200.
