Question 128002
Length  = {{{l}}}
Width = {{{w}}}
{{{w = x}}}
{{{l = 3x - 5}}}
{{{P = 2w + 2l}}}
{{{60 = 2x + 2(3x - 5)}}}
{{{60 = 2x + 6x - 10}}}
{{{8x = 70}}}
{{{x = 8.75}}}
{{{w = 8.75}}}
{{{l = 3x - 5}}}
{{{l = 3*8.75 - 5}}}
{{{l = 21.25}}}
Width is 8.75 inches and length is 21.25 inches
check:
{{{60 = 2x + 2(3x - 5)}}}
{{{60 = 2*8.75 + 2(3*8.75 -5)}}}
{{{60 = 17.5 + 2(26.25 - 5)}}}
{{{60 = 17.5 + 42.5}}}
{{{60 = 60}}}
OK
