Question 179285
A rectangle perimeter is twice the length plus twice the width.
{{{P=2L+2W>=136}}}
{{{L=4+W}}}
.
.
.
{{{2L+2W>=136}}}
{{{2(4+W)+2W>=136}}}
{{{8+2W+2W>=136}}}
{{{4W>=128}}}
{{{W>=32}}}
The width must be at least 32m.
{{{L=W+4}}}
{{{L>=36}}}
The length must be at least 36m.
Check your question again, are you sure they're not asking for the range of values for the length and not the width???
