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%28x%2By%29%3C=+300

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

2%28y%2B125%29%3C=300
2%28y%2B125%29%2F2%3C=300%2F2
y%2B125%3C=150
y%3C=25

Thus, the maximum measure of the width is 25 inches
