Question

the cost of flooring a room at rupees 9.40 per square metre is 564 if the length of room is 8 m than what is it breadth ​

Answer 1

Answer:

so the breadth of floor is 7.5 metre

Step-by-step explanation:

cost/m=9.40

total cost = 564

length=8m

from total cost we will find out the total area of floor.

so, (total cost/cost of 1 sq.m)=area of floor

564/9.40=area of floor

60=area of floor

area of floor is l*b

l=8 m

b*8=60

b=60/8

b=15/2

b=7.5 m
