long wire is broken into two unequal parts

\mathrm{X}

and

\mathrm{Y}

. The

\mathrm{X}

part of the wire is streched into another wire W. Length of

W

is twice the length of

X

and the resistance of

\mathrm{W}

is twice that of

\mathrm{Y}

. Find the ratio of length of

\mathrm{X}

and

\mathrm{Y}
