Question 646732


The length of a rectangle {{{L}}} is {{{5}}} centimeters {{{greater}}} than its width {{{W}}}.

{{{L=W+5cm}}}

The perimeter {{{P}}} is {{{58cm}}}.

{{{P=2(L+W)}}}....substitute {{{L=W+5cm}}} and {{{P=58cm}}}

{{{58cm=2(W+5cm+W)}}}

{{{58cm=2(2W+5cm)}}}

{{{58cm=4W+10cm}}}

{{{58cm-10cm=4W}}}

{{{48cm=4W}}}

{{{48cm/4=W}}}


{{{highlight(12cm=W)}}}...now find {{{L}}}

{{{L=W+5cm}}}

{{{L=12cm+5cm}}}

{{{highlight(L=17cm)}}}
