Question

10) A square dais is of area 92.16 m². What is
the measure of its side? If tiles measuring
12 cm x 12 cm are laid on the dais, find the
number of tiles needed to pave it.​

Answer 1

Area of square =side²

92.16m²=a²

a=9.6m

area of tile =0.12mx0.12m

=0.144m²

no. of tile=92.16/0.144

=640

THANKS!!!

Answer 2

Answer:

$area \: of \: square \: = side {}^{2} \\ 92.16m {}^{2} = side {}^{2} \\ side = \sqrt{92.16m {}^{2} } \\ side = 9.6m. \\ area \: of \: tiles \: = 0.12m \times 0.12m \\ 0.144m {}^{2} \\ so \: number \: of \: tiles \: = \frac{92.16}{6.144} = 640 \: \: \: \: \: \: \: \: \: \: ans.$
