help me to find the answers ​

Answer 1

Answer:

No. of tiles =Area of floor/Area of one tile=1080/90=12 tiles

Answer 2

Correct Question-:

• A flooring tile has the shape of a parallelogram whose base is 9 cm and the corresponding height is 10 cm . How many tiles are required to cover a floor of area 1080 m² .

AnswEr -:

• .$\underline{\boxed{\star{\sf{\blue{The \:tiles\:need\: to\: cover\: a\:floor\:of\:an\:area\:of\:1080m^{2}= 1,20,000}}}}}$

EXPLANATION-:

• $\frak{Given \:\: -:} \begin{cases} \sf{The\:base\:of\:Parallelogram \:shaped\:tiles\:is\:= \frak{9cm\:}} & \\\\ \sf{ The\:Height \:of\:Parallelogram \:shaped\:tiles\:is\:\:=\:\frak{10cm}}& \\\\ \sf{ The \:tiles\:need\: to\: cover\: a\:floor\:of\:an\:area\:of\:1080m^{2}}\end{cases}$

• $\frak{To \:Find\: -:} \begin{cases} \sf{How\:many\: \:tiles\:need\: to\: cover\: a\:floor\:of\:an\:area\:of\:1080m^{2}}\end{cases}$

• .$\underline{\boxed{\star{\sf{\blue{  Area \:of\:Parallelogram \:is\: = Base\times Height.}}}}}$

• $\frak{Here \:\: -:} \begin{cases} \sf{The\:base\:of\:Parallelogram \:shaped\:tiles\:is\:= \frak{9cm\:}} & \\\\ \sf{ The\:Height \:of\:Parallelogram \:shaped\:tiles\:is\:\:=\:\frak{10cm}}\end{cases}$

Now ,

• $\implies{\sf{\large {Area_{Parallelogram} = 10 \times 9 }}}$
• $\implies{\sf{\large {Area_{Parallelogram} = 90cm^{2} }}}$

Therefore,

• .$\underline{\boxed{\star{\sf{\blue{  Area \:of\:Parallelogram \:is\: = 90cm^{2}.}}}}}$

• Number of tiles = Area need to cover by tiles / Area of Parallelogram tiles .

• Area of Parallelogram tiles = 90 cm²
• The tiles are required to cover a floor of area 1080 m² .
• [ 10000cm² = 1m² ]
• Then,
• The tiles are required to cover a floor of area 1080 m² = 1080 × 10000 cm²

Now ,

• $\implies{\sf{\large {Number_{Parallelogram\: tiles} = \frac{1080 \times 10000}{90} }}}$
• $\implies{\sf{\large {Number_{Parallelogram\: tiles} = \frac{1080 \times 1000}{9} }}}$
• $\implies{\sf{\large {Number_{Parallelogram\: tiles} = 120 \times 1000 }}}$
• $\implies{\sf{\large {Number_{Parallelogram\: tiles} = 120,000 }}}$

Hence ,

• .$\underline{\boxed{\star{\sf{\blue{The \:tiles\:need\: to\: cover\: a\:floor\:of\:an\:area\:of\:1080m^{2}= 1,20,000}}}}}$
