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

hey mate here is your answer.


let the breadth be X m
therefore length=2X m

A/Q
c.s.a of cylinder =1250m square
cylinder is form from a rectangular metaliic sheet
therefor area of metallic sheet = c.s.a. of cylinder
so, length × breath = 1250
2X×X=1250
2X^2=1250
X^2=1250÷2
X^2=625
therefore X =25
so, the breadth=25m and
lenght=50m
as, the dimension of rectangular sheet =50m×25m

(here m=meter and ^2=power two or square)

hope it helps you.
