Question

a cylinder of csa area 1250m square is formed from a rectangular metallic sheet.find the dimension of the rectangular sheet if the length is double its breadth.

tell me the solution

Answer 1

hiii!!!

here's ur answer...

CSA of the cylinder=area of the rectangle

given that the length is double of it's breadth.

so the breadth of the rectangle be x and length be 2x.

area of the rectangle=1250m²

l×b=1250m²

2x×x=1250m²

2x²=1250m²

x²=1250/2

x²=625

x=√625

x=25

hence, breadth of the rectangle=x

=25m

length of the rectangle=2x

=2×25

=50m

hope this helps...
