$\huge{\underline{\underline{\red{\mathfrak{AnSwEr :}}}}}$

$\small{\underline{\blue{\sf{Given :}}}}$

P = 2l + W

$\rule{200}{1}$

$\small{\underline{\green{\sf{Solution :}}}}$

$\implies {\sf{P \: = \: 2l \: + \: W}} \\ \\ \implies {\sf{2W \: = \: P \: - \: 2l}} \\ \\ \implies {\sf{W \: = \: \dfrac{P \: - \: 2l}{2}}}$

Answer is A

• Here the only basics of the equation solving are used.
• Just Cross multiply
