Question 644251


a rectangle's length {{{L}}} is {{{5yd}}} more than {{{3}}}{{{ times}}} its width {{{W}}}



find an expression for the perimeter {{{P}}} of the rectangle 

we know that the perimeter {{{P}}} of the rectangle is:

{{{P=2(L+W)}}}..........

it,s given that {{{L=3W+5yd}}}...replace it in {{{P}}}

{{{P=2(3W+5yd+W)}}}

{{{P=2(4W+5yd)}}}
