Answer 2

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\dashrightarrow length \:of\:carpet= 75\:cm \\ \therefore \:converting\:in\:m\\ \dashrightarrow \dfrac{75}{100} \\ \implies 0.75m$

$\dashrightarrow breadth\:of\:floor= 12m$

$\dashrightarrow length\:of\:floor= 8m$

$\therefore it \:is\:said\:that\: area\:of\:floor\:is\:equal\:to\:area\:of\:carpet\: \\ \large{ EQUATION\:FORMED,} \\ \dashrightarrow area\:of\:floor= area\:of\:carpet.$

$\large\underline\bold{TO\:FIND,}$

$\dashrightarrow carpet\:required\:to\:cover\:the \:floor.$

$\large\underline\bold{SOLUTION,}$

$\dashrightarrow let\:the\:breadth\:of\:caroet\:be\:x\:m$

$\dashrightarrow solving\:the\:equation.we\:get$

$\implies 12 \times 8= 0.75 \times x$

$\implies x= \dfrac{12 \times 8}{0.75}$

$\implies x= \dfrac{96}{0.75}$

$\implies x= \cancel \dfrac{96}{0.75}$

$\implies x= 128m$

$\large{\boxed{\bf{ \star\:\: x=128 m\:\: \star}}}$

$\large\underline\bold{128\:m\:OF\:CARPET\:WILL\:BE\:REQUIRED. }$
