Question

1. A rectangular hall is 5.25 m long and 3.78 m wide. It's floor is to be covered with square tiles, each of side 21 cm. Find the cost of tiles required at the rate of ₹5 per tile.

Solution

$\sf{Since, \: \: floor \: area \: of \: hall=5.25 \: m × 3.78 \: m} \\ \sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =525 ×378 \: cm²} \\ \sf{And, \: \: area \: of \: each \: tile=21 ×21 cm²} \\ \sf{Number \: of \: tiles \: required=\dfrac{Floor \: area \: of \: hall}{Area \: of \: each \: tile}} \\ \sf{\dfrac{525×378}{21×21}=450} \\ \sf{Since, \: \: \: cost \: of \: each \: tile \: =₹5} \\ \\ \sf{→The \: cost \: of \: all \: the \: tiles \: required=450×₹5=₹2,250}$
