Question

flouring tile has the shape of a parallelogram whose base is 23cm and the corresponding height
is 10cm. how many such tiles are required to cover a floor of area 1080m^2.​

Answer 1

$\huge \color{lime}\underline{\overline{\mid{\bold{\color{aqua}{Answer}}\mid}}}$

Area of parallelogram= B×H

Area = 23×10=230cm²

Tiles required to cover the area of 108m²

1m²=10000cm²

1080m²= 10800000cm²

$\sf \: Tiles \: required = \frac{10800000}{240} = 45000$

So 45000 tiles of 240cm² are required to cover 1080m²

Hope it helps you.....
