Question

how many tiles whose length and breadth are 12 cm and 5 cm respectively and needed of it in a rectangular region whose length and breadth are 144 cm and 100 cm respectively

Answer 1

area of one tile 12×5=60
area of the rectangle region=144×100=14400
no. of tiles needed=14400÷60=240 tiles.
hope this helps you

Answer 2

Answer :

(a) We know that,

Area of rectangle = Length × Breadth

It is given in the question that,

Length = 100 cm

Breadth = 144 cm

Therefore,

Area = Length × Breadth

= 100 × 144

= 14400 cm^2

Therefore,

Area of one tile = 12 × 5

= 60 cm^2

Hence,

Number of tiles required = 14400/60

= 240

Therefore, total 240 tiles are required
