Solution

Area of rectangular sheet = lateral surface area of hollow cylinder = 4224 cm^2.
Area of rectangle = length x width.
Let l = length of sheet in cm. Width of sheet = 33 cm (given)
Then l x 33 = 4224
l = 4224/33= 128 cm.
Perimeter of rectangular sheet = 2(length + width) = 2( 128+33) = 2(161) = 322 cm
Answer: 322 cm
