Question

How many tiles of length 12cm and breadth 5cm will be needed to cover a rectangular region whose

length and breadth are 1m and 144 cm respectively​

Answer 1

Answer:

240

Step-by-step explanation:

Area of rectangular region = length × breadth

= 1 m × 144 cm = 1 × 1.44 = 1.44 sq. m.

Area of tile = (12 cm) × (5 cm) = (0.12 m) × (0.05 m)

= 0.0060 = 0.006 sq. m.

Number of tiles = Area of region/Area of tile

$\frac{1.44}{0.006} = \frac{1.440}{0.006} = \frac{1440}{6} = 240$

Therefore 240 tiles are required.
