Question

a carpet is 30 m 75 cm long 80 cm wide. Find its cost at Rs 150 per square m​

Answer 1

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 m2

∴ Area of carpet = 24.6 m2

It is given that the cost of 1 m2 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.

Answer 2

length =30.75m

bredth=80cm

area=2460m^2

cost per square =150

therefore cost=150×2460=3 69000
