Question

A cylinder of curved surface area 1250msquare is formed from a rectangular metallic sheet. Find the dimensions of the rectangular sheet if its length is double its breadth.

Answer 1

curved surface area of cylinder=1250m.sq.
curved surface area=area of rectangular sheet
sheet breadth= x
sheet length=double its breadth
length=2x
x*2x=1250
x^2=625
x=25
breadth=25m
length=50m
