Question

Find the cost of polishing a room of length 12m and breadth 8m at Rs 25 per square meter.

Answer 1

Step-by-step explanation:

Area of room = l x b

= 12 x 8 = 96m square

Rate of polishing per m square = Rs 25

Cost of polishing 96 m square = Rs (96 x 25)

= Rs 2400.

Answer 2

Answer:

2,400

Step-by-step explanation:

length= 12m

breadth= 8 m

so for taking out the cost of polishing a room first we need to takeout the area of the square

area of square= l × b

= 12× 8

= 96 sq.m

cost of polishing on one sq.m = 25

cost of polishing on 96 sq.m is= 96×25

= 2400
