Question

A room is 20 m long and 15 m broad. Find the cost of carpeting its floor if 1 sq cm of carpet costs rs.2.00

Answer 1

Answer:

Step-by-step explanation:

length of room = 20 m

breadth of room = 15 m

area of room = length × breadth

                        = 20 × 15

                         = 300 m²

cost per unit = rs 2

cost of carpeting of floor = area of room × cost per unit

                                            = 300 m² × 2

                                             =  ₹600
