Question

If a square tiles of side 1 cm is covered the rectangular field of 5 M in length and 10 M in breath then find the number of tiles required​

Answer 1

Solution:

(a) Area of region = 100 cm x 144 cm = 14400 cm.sq

Area of one tile = 5 cm x 12 cm = 60 cm.sq

Number of tiles = \frac{Area\ of\ region}{Area\ of\ one\ tile} = 240

Thus, 240 tiles are required.

(b) Area of region = 70 cm x 36 cm = 2520 cm.sq

Area of one tile = 5 cm x 12 cm = 60 cm.sq

Number of tiles = \frac{Area\ of\ region}{Area\ of\ one\ tile} = 42

Thus, 42 tiles are required.

Answer 2

Answer:

side of square tiles = 1 cm

length of the rectangular field = 5m

breadth of the rectangular field = 10m

Area of the rectangular field = length x breadth

= 5 m x 10m = 50 m²

1 m² = 10000 cm²

50 m² = 10000 x 50 = 500000 cm²

So, the rectangular field required 5,00,000 tiles.
