Question

a floor of length 25 m and breadth 20 m has to be paved with rectangular tiles of length 16 cm and breadth 5 cm find the number of tiles required​

Answer 1

total area of floor=2500cm*2000cm=5000000sq.cm

Req. no. of tiles=5000000sq.cm/16cm*5cm=62500

Answer 2

${\green{\mathbb{HOLA!!}}}$

Given:-

Measurements of floor
L=25m or 2500cm
B=20m or 2000cm

Measurements of tile
l=16 cm
b=5cm

Tiles required=${\frac{Area\:of\: floor}{Area\:of\:tiles}}$

Area of floor=L×B
=2500×2000
=50,00,000cm²

Area of tile=l×b
=16×5
=80cm²

Number of tiles =${\frac{50,00,000}{80}}$

${\red{Tiles\: required=62500}}$
