Question 108309


perimeter=2*(length+width)


Let x=length
____y=width
____2(x+y)=perimeter


The perimeter of a rectangle is to be no greater than 300 in., 

{{{2(x+y)<= 300}}}


But, {{{x=125}}} (the length must be 125 in).So,


{{{2(y+125)<=300}}}
{{{2(y+125)/2<=300/2}}}
{{{y+125<=150}}}
{{{y<=25}}}


Thus, the maximum measure of the width is 25 inches
