Question

A wire is in the shape of a rectangle its length is 20 cm and the breadth is 16 cm if the same wire is read band in the shape of square what will be the measure of each said​

Answer 1

$\huge\mathtt{✭\:Solution\: -:}$

⠀ ⠀⠀ ⠀ ⠀⠀

$\tt{Given \:A \:wire \:is\: in\: shape \:of \:rectangle }$

↦$\tt{where}$

↦$\tt{length\:=\:20 cm. }$

↦$\tt{breadth\:=\:16 cm.}$

↦$\tt{Perimeter\: of\: rectangle\: =\:2(l+b)}$

↦$\tt{\:2(36)}$

↦$\tt{[Perimeter \:=\:72 cm.]}$

$\tt{Now \:of \:wire\: is \:bent \:in\: shape\: of \:square}$

↦$\tt{where \:side \:=\:a \:cm}$

↦$\tt{now }$

$\tt{Perimeter \:of \:rectangle \:=\: perimeter }$$\tt{of \:square }$

↦$\tt{72\:=\:4\:a}$

↦$\tt{[a\:=\:18\:cm]}$

$\tt{Side \:of\: square\: formed\: is\: 18 \:cm.}$
