Question 899714
Let {{{ p }}} = perimeter of fence
{{{ 100 <= p <= 190 }}}
{{{ p = 2W + 2L }}}
{{{ L = 22 }}}
{{{ 2L = 44 }}}
{{{ p = 2W + 44 }}}
-----------------
{{{ 100 <= 2W + 44 <= 190 }}}
Subtract {{{ 44 }}} from the 3 parts
of inequality
{{{ 56 <= 2W <= 146 }}}
Divide through by {{{ 2 }}}
{{{ 28 <= W  <= 73 }}}
---------------------
check:
suppose {{{ W = 73 }}}
{{{ 2W = 146 }}}
{{{ 2L = 44 }}}
{{{ p = 146 + 44 }}}
{{{ p = 190 }}}
You can check lower limit
