Question

A cylinder of curved surface area 1,250m2 is formed from a rectangular metalic sheet.Find the dimensions of a rectangular sheet if its length is doubled its breadth

Answer 1

Hope it helps!!!

C. S. A. Of cylinder= Area of the rectangular sheet

Therefore, 1250 =l×b
1250 =2b×b [since l=2b]

=>b^2=1250/2
=>625

Therefore, b=25m

And l=25×2
=50m
