• Total length of two pieces :

${ }$

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{\dfrac{2}{5}}\:+\:1{\dfrac{3}{4}}$

${ }$

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{\dfrac{2}{5}}\:+\:{\dfrac{7}{4}}$

${ }$

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{\dfrac{8\:+\:34}{20}}$

${ }$

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{\dfrac{43}{50}}$

${ }$

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{2.15\:m}$

${ }$

Therefore,

${ }$

• ${\blue{\mathfrak{Length\:of\:rope\:remaining\:\leadsto\:Total\:length\:of\:rope\:-\:Two\:pieces\:of\:length}}}$

${ }$

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{5\:-\:2.15}$

${ }$

$\:\:\:\:\:\:\::\:\Longrightarrow\:{\underline{\boxed{\frak{\pink{2.85\:m}}}}}\:\bigstar$

${ }$

${ }$

$\:\:\:\:\therefore\:{\underline{\sf{Hence,\:the\:rope\:is\:left\:are\:{\textsf{\textbf{2.85\:m}}}}}}.$
