Question

Find the cost of covering the floor of a 6.5m long and 5m broad room with 25 cm square tiles at 470 per 100 tiles ?

Answer 1

HEYA MATE, HERE IS UR ANSWER


$<b><i>Area of the floor=length ×breadth of the floor$

=6.5×5

= 32.5 m^2

=32.5×10,000 cm^2

=325000 cm^2

Area of 1 tile=25 cm^2


Number of tiles =$\frac {Area\:Of \:floor}{Area\:of\:one\:tile}$

= $\frac {325000}{25}$

= 13,000 tiles

Cost of 100 tiles=Rs 470

Cost of 1 tile=Rs $\frac {470}{100}$

= Rs 4.7

Cost of 13,000 tiles=Rs 4.7×13,000

=Rs 61,100

So the cost is Rs 61,100 .
