Answer 1

$\huge{\underline{\sf{Question :-}}}}$

A square length is 400 cm and the breadth is 400 cm. What will be the area and perimeter?

$\huge{\underline{\sf{Answer :-}}}}$

$\sf Given\begin{cases} &\sf{Length\;of\;the\; square, \;l\;=\be{400\:cm}}\\&\sf{Breadth\;of\;the\;square,\;b\;=\bf{400\;cm}}\end{cases}$

$\boxed{ \sf \blue{ To \: Find : }}$

• Area of the square = ❓
• Perimeter of the square = ❓

$\green{\underline\bold{Now,}}$

✏ Let 'a' be the side of the square,

where a = 400cm

$\green{\underline\bold{We \:know,}}$

$\boxed{ \sf \blue{ Area\: of \:a \:square \:= \:a^\:2.}}$

= (400)^2

= 160000

$\green{\underline\bold{And,}}$

$\boxed{ \sf \blue{ Perimeter\: of \:a \:square \:= \:4\:a.}}$

= 4 × 400

= 1600

$\pink{\underline\bold{∴\: Area \:of \:the\: square \:= \:160000.}}$

$\pink{\underline\bold{ Perimeter\: of\: the\: square \:= \:1600.}}$
