Answer 1

Step-by-step explanation:

area of wall =4.41x3.5

=15.435m^2

area of tiles =21 x 7

=147cm^2

since 1mtr =100 cm

therefore 147 cm =147 /100=1.47

no. of tiles =15.435/1.47=10.5

therefore 10.5 tiles are required to plaster the wall

105 tiles

Step-by-step explanation:

Hey Mate, Nice Question. And Here You Go Dude.....

Length of wall= 4.41 m. = 441 cm.

Height of wall= 3.5 m. = 35 cm.

Area of wall = 15435 sq. cm.

Length of tile= 21 cm.

Height of tile= 7 cm.

Area of tile = 147 sq. cm.

No. of tiles required= (15435/147) tiles

= 105 tiles.
