and 14m long, is to be polished. The charges for
Polishing are 52 per sq. m. what will be the cost of
Polishing the floor of the classroom?​

Answer 1

Answer:

Cost = 7280 Rs

Step-by-step explanation:

l = 14 m

b = 10 m

Area of floor(rectangle) = l x b

                                       = 14 x 10

                                       = 140 sq. m

Cost for 1 m = 52 Rs/m

Cost for 140 m = 140 x 52

                        = 7280 Rs
