Question

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

Answer 1

Given,

Length of carpet = 30m 75 cm

= 3075 cm

And, Breadth of carpet = 80cm

Now, Remember

area of rectangle = length × breadth

So, According to the question

Area of carpet = 80cm× 3075 cm

=>area of carpet= 246,000cm^2

hence, area of carpet is 246,000cm^2.

i.e (246000/10000)m^2 = 24.6m^2

now ,

cost of 1m^2 carpet = Rs150

hence,Cost of 246 m^2 = 150× 24.6

= Rs 3690.0

So the cost of the carpet is Rs 3690.

Answer 2

Length = 30m75cm = 3075 cm

Breadth = 80 cm

so , area of this rectangle = l × b

= 3075×80

= 30750×8

= 246000 cm ^2

= 2460 m^2

so , cost shall be ,

2460×150

369000 rupees

hope it works ✌️
