Question

how many tiles of length and breadth 20cm and 8cm respectively can fit on a rectangular floor of length 16m and breadth 12 m? explain​

Answer 1

Answer:

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}

Area of one tile

Area of region

= 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}

Area of one tile

Area of region

= 42

Thus, 42 tiles are required.
