hiii!!!
here's ur answer...
given the lateral surface area(CSA) of the hollow cylinder is 4224cm².
if it's cut along the side then it form a rectangle it means the area of rectangle is 4224cm²
breadth=33cm
l×b=4224cm²
l×33=4224cm²
l=4224/33
l=128cm
hence,the length of the rectangle is 128cm.
therefore perimeter of the rectangle=2(l+b)
=2(128+33)
=2×161
=322cm
hope this helps...
