Question

Draw many tiles with dimensions 5cm and 12cm will be needed to fit in a region whose length and breath are 150 cm and 144cm.

Answer 1

let the length and breadth of the region be L and B.

let the length and breadth of 1 tile be l and b.

area of the region=L*B

                             =150*144

                             =21600 sq. cm

area of 1 tile=l*b

                   =5*12

                   =60 sq. cm

no. to tiles=(area of the region)/(area of 1 tile)

                 =21600/60

                 =360

therefore, 360 tiles are needed to be fit in the rigion.
