Answer 2

Answer:

651 and Half bands would be needed.

Step-by-step explanation:

Area of Floor = 52.12 x 10

                       = 521.2 metres

                       = 521.2 x 100 cm

                       = 52120 cm

Area of one band = 10 x 8

                             = 80 cm

∴ No. of bands required to cover the room = $\frac{52120}{80}$

                                                                        = 651.5 bands.

Hence, 651 bands and a half band would be needed to cover the entire floor.
