# A carpet is 30 m 75 cm long and 80 cm wide. Find its cost at Rs. 150 per square meter.

Answer :

Given:

Length of the carpet = 30 m 75 cm

We have 100 cm = 1 m ⇒ 75 cm = 0.75 m

⇒ Length of carpet = (30 + 0.75) m = 30.75 m

Width of the carpet = 80 cm = 0.80 m

We know, **area of rectangle = length × breadth**

⇒ Area of carpet = 30.75 × 0.80 m^{2}

∴ Area of carpet = 24.6 m^{2}

It is given that the cost of 1 m^{2} carpet is Rs. 150.

⇒ Cost of carpet = Rs. 150 × 24.6

∴ Cost of carpet = Rs. 3690

Thus, **the cost of the carpet is Rs. 3690.**
