☯ Let length is l and breadth is b.

${ }$

$\:\:\:\:\:\:{\bold{\dag}}\:{\sf{As\:We\:Know\:That\::}}$

${ }$

$\:\:\:\:\:\:\:\:\:\:\:\:\:{\green{\bigstar}}\:{\sf{\bf{Ratio\:=\:{\dfrac{Length}{Breadth}}}}}$

${ }$

$\:\:\:\:\:\:\:\dashrightarrow\:\sf{\dfrac{13}{7.8}}$

${ }$

$\:\:\:\:\:\:\:\dashrightarrow\:\sf\cancel{\dfrac{130}{78}}$

${ }$

$\:\:\:\:\:\:\:\dashrightarrow\:\sf{\dfrac{5}{3}}$

${ }$

$\:\:\:\:\:\:\:\dashrightarrow\:{\underline{\boxed{\frak{\pink{5\::\:3}}}}}\:\bigstar$

${ }$

${ }$

$\:\therefore\:{\underline{\sf{Hence,\:the \:ratio \:of\: its\: length\:to \:its \:breadth\:is\:{\textsf{\textbf{5\::\:3 }}}}}}.$
