Question 980089


to find the perimeter of the triangle {{{72in}}}, {{{51in}}}, and {{{1yd}}}, first convert {{{1yd}}} into inches

{{{1yd=36in}}} 

so,  the perimeter of the triangle is {{{P=72in+51in+36in=159in}}}


or, you can convert inches into yards

{{{72in=(72/36)yd=2yd}}}, {{{51in=(51/36)yd=1.416666666666667yd=1.42yd}}}, 

and {{{P=2yd+1.42yd+1yd=4.42in}}}
