here is your answer ☺☺☺☺☺☺☺
A hollow cylinder is cut along its height to form a rectangular sheet.
⇒ Area of cylinder = Area of rectangular sheet = 4224 cm2
⇒ 4224 cm2 = 33 cm × Width
⇒ 4224/33=128cm
Thus, the Width of the rectangular sheet is 128 cm.
Perimeter of the rectangular sheet = 2 (Length + Width)
= [2 (128 + 33)] cm = (2 × 161) cm
= 322 cm
