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 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.
