1 metre = 100 centimetres
Area = 100 x 40 = 4000 cm2
Area of each tile = 10x 10 = 100 cm2
Number of tiles required = 4000/100 = 40 tiles
Alternatively, 10 tile lengths = 1 metre : 4 tile lengths = 40 cm
Number of tiles required = 10 x 4 = 40
40 cm (10cm x 4 sides = 40cm)
It is: 70cm+1m 40cm = 2m 10cm
The perimeter of 100 square in cm is 40cm. Each side is 10cm, you get 40 when you add the four sides.
I don't suppose you considered the fact that the answer would depend on whether the tiles are 40cm*40cm or 40 inch*40 inch or 40*40 in some other units.
You would need a total of 207 tiles. 196 whole tiles 7 tiles cut into 28 40-cm x 10-cm pieces 3.5 tiles cut into 28 40-cm x 5-cm pieces four 10-cm x 5-cm pieces cut from the remaining half tile
40cm (4 x 10 = 40)
If one side is 10cm...10 x 4 = 40cm
Perimeter = 40cm. Area = 100cm2
40 cm (10cm x 4 sides = 40cm)
It is: 70cm+1m 40cm = 2m 10cm
The perimeter of 100 square in cm is 40cm. Each side is 10cm, you get 40 when you add the four sides.
The perimeter is 40cm
It is: 20*40*10 = 8,000 cubic cm
I don't suppose you considered the fact that the answer would depend on whether the tiles are 40cm*40cm or 40 inch*40 inch or 40*40 in some other units.
P = 160cm
They're the same amount because 10cm= 1dm and 10x4=40 and 1x4=4 and 4dm= 40cm
You would need a total of 207 tiles. 196 whole tiles 7 tiles cut into 28 40-cm x 10-cm pieces 3.5 tiles cut into 28 40-cm x 5-cm pieces four 10-cm x 5-cm pieces cut from the remaining half tile
