Question

How many tiles with dimensions 14cm and 9cm will be needed to fit a region whose length and breadth are 168cm and 72cm​

Answer 1

Answer:

168x72 divided by 14x9

Answer 2

Length of region = 168 cm

Breadth of region = 72 cm

Area of region = (168 × 72) cm

= 12096 Sq cm

Length of tiles = 14 cm

Breadth of tiles = 9 cm

Area of tiles = (14 × 9) cm

= 126 Sq cm

= (area of region÷area of tiles)

=12096 ÷ 126

= 96

Hence the number of tiles needed to cover the floor=96 tiles....

Hope it helps.
