Answer»

Answer:

Side of sheet = 30 CM

$\boxed{ \blue{ \bf <klux>AREA</klux> \: of \: Sheet = {a}^{2} }} \\ \\ \Longrightarrow30 \times 30 \\ \\ \Longrightarrow 900 {cm}^{2}$

6 cm strip is cut from all side , then side will be reduced by 12 cm

Side of new sheet = 18 cm

$\boxed {\bf \blue{ Area \: of \: new \: Sheet = {a}^{2} }} \\ \\ \Longrightarrow 18 \times 18 \\ \\ \Longrightarrow324 {cm}^{2}$

Area of strip :

Area of sheet - Area of new sheet

$\Longrightarrow900 - 324 \\ \\ \boxed{\bf \green{Strip's \: Area = 576 \: {cm}^{2} }}$
