Best answer

A hollow cylinder is cut along its height to form a rectangular sheet.

Area of cylinder = Area of rectangular sheet

4224 cm2 = 33 cm × Length

Lenght = 4224 cm2/33 cm = 128cm

Thus, the length of the rectangular sheet is 128 cm. Perimeter of the rectangular sheet = 2 (Length + Width)

= [2 (128 + 33)] cm

= (2 × 161) cm

= 322 cm
