$\Large{\blue{\tt{\underline{\underline{Given \ :-}}}}}$

${\sf{☞ \ l \ = \ 4x}}$

${\sf{☞ \ b \ = \ 2x}}$

$\Large{\green{\tt{\underline{\underline{To \ find \ :-}}}}}$

${\sf{\bold{• \ Value \ of \ x}}}$

$\Large{\purple{\tt{\underline{\underline{Formula \ used \ :-}}}}}$

${\sf{⟹ \ Perimeter \ of \ rectangle \ = \ 2(l+b)}}$

$\Large{\orange{\tt{\underline{\underline{Solution \ :-}}}}}$

${\sf{↣ \ Perimeter \ of \ rectangle \ = \ 2(length+breadth)}}$

${\sf{↣ \ 72 = 2(4x + 2x)}}$

${\sf{↣ \ 72 = 8x + 4x}{$

${\sf{↣ \ 72 = 12x}}$

${\sf{↣ \ x = \frac{72}{12} }}$

${\sf{↣ \ x = 6}}$
