Question 1206312

if a wire is first bent into the shape of a rectangle with width {{{9in}}}  and length {{{12in}}}, then the perimeter is 

{{{2(9in+12in)=2+21in=42in}}}


if the wire is unbent and reshaped into a triangle, then a triangle will have {{{same}}}{{{ perimeter}}} as rectangle

if each side  of the triangle has equal length of {{{x}}}, then

{{{3x=42in}}}

{{{x=42in/3}}}

{{{x=14in}}}


this length of each side of triangle is {{{14in}}}
