Question

how many tiles,whose length and breadth are 10cm and 20cm respectively ,will be needed to fit a floor of area 60cm×100cm​

Answer 1

Answer:

30 tiles

Step-by-step explanation:

area of tile= length*breadth

=10*20

=200cm2

area of floor= 60*100

=6000cm2

no. of tiles required= area of floor/area of 1 tile

6000/200

=30 tiles

Answer 2

area of tile = length ×breadth

=10 ×20

=200 sq. cm

area of floor = length ×breadth

=60×100

=6000 sq. cm

number of tiles needed = area of floor \ area of tiles

$= \frac{6000}{200} \\ = \frac{60}{2} \\ = \frac{30}{1} \\ = 30$
