Question

the total cost of flooring at room at 80. 50 per square metre is rupees 4830 if the length of the room is 8 M find its breadth​

Answer 1

Answer:

breadth=7.5 m

Step-by-step explanation:

Total Cost=Rs. 4830

Cost per sq. meter=Rs. 80.50

Then,

    Area of room=4830/80.50

                           =60 m^2

Area of room=l*b

 or,60= 8 * b

or,b=60/8

therefore b= 7.5 meter
