Question

A cylinder of curved surface area 1152 sq m is formed from a rectangular metallic sheet. Find the dimensions of the rectangular sheet if its length is double of its breadth.

Answer 1

Step-by-step explanation:

first let the length be 2x

and breadth be x

now both figures have same area

so, 2X×X=1250

2Xsquare=1250

Xsquare=1250/2=625

X=

\sqrt{625}

625

X=25

then put the value of X in length and breadth

length =50m, breadth =25m

hope it will help you

Answer 2

Answer:

let the lenght be 2x

and breadth be X

then 2X×X =1152

2x^2=1152

x^2 =1152/2

x^2= 576

then, x=√576

x= 24.

A/q length = 2x

then ,2×24

=48

breadth, x= 24
