Question

How many square tiles with dimension 6 cm can be fixed on a small surface whose length and breadth are 42 cm and 30 cm
respectively?
( hint : 35 is the answer)

Answer 1

Answer:

Area of floor = 42×30 = 1260 sqcm

area of tiles:6x6=36 sqcm

No of tiles:1260/36=35 tiles.

Answer 2

Answer:

area of 1 tile = $6^{2} =36$

area of surface $= 42*30 =1260$

no. of tiles that can be fixed = area of surface/area of 1 tile =$1260/36 =35 tiles$
