Question

how many metres of carpet 63 cm wide will be required to cover the floor of a room 14m by 9m​

Answer 1

Answer:

Step-by-step explanation:

Area of room = 14 * 9

                       = 126m²

As 1m = 100cm

                        = 126 * 10000 cm²

                         

length of carpet

                        = 126 * 10000 / 63

                        = 20000 cm

                        = 20000 / 100

                        = 200 m
