The rectangular floor measures 3m by 2m. The area of the floor is 6 m^2. It is covered by 384 square tiles. If the side length of each tile is x cm., the area of one tile is x^2*10^-4 m^2
This gives 384*x^2*10^-4 = 6
=> x^2 = 6*10^4/384
=> x^2 = 60000/384
=> x^2 = 156.25
=> x = 12.5
The length of the side of the tiles is 12.5 cm.
Floor area = 3m * 2m = 6 m2
No. of tiles covering the floor = 384
Area of each tile = 6/384 = 0.012525 m2 = 125.25 cm2
let x be the side length of a tile in cm
x^2 = 125.25 cm2
x = 12.5 cm
Length of the side of a tile is 12.5 cm
Let the no. of tiles in lengthwise be 'x'.
length of the room is 3 metres=300 cm
Hence length of the side of each tile = 300/x cm.
Let the no. of tiles in breadthwise be 'y'.
breadth of the room is 2 metres = 200 cm.
Hence length of the side of each tile = 200/y cm.
Since the tiles are square 300/x = 200/y
Hence x/3 = y/2 or x= 3/2y.
Total no. of tiles=xy=384.
3/2 y^2 =384
y^2 =384 * 2/3 =256
no. of tiles =24*16 =384 (verified)
Hence length of the side of each tile = 300/24 =100/8=12.5 cm.
Answer: side length of each tile = 12.5 cm.
