A room 6m long and 4m wide needs 1000 tiles for its floor. How many tiles will be nedded for a hall 12m long and 8m wide?
Length = 6m, Breadth = 4m
Area = 6 x 4 = 24m2
Second Hall Length = 12m
Breadth = 8m
Area = 12 x 8 = 96m2
We can use proportional method. Let a be the number of tiles required for the second hall.
24 : 1000 :: 96 : a
24a = 1000 x 96
a = 1000 x 96/24
a = 4000 tiles
