Question 1125619
{{{ P = 2L + 2W }}}
{{{ L = W + 123 }}}
{{{ P = 2*( W + 123 ) + 2W }}}
{{{ P = 2W + 246 + 2W }}}
{{{ P = 2438 }}}
{{{ 4W + 246 = 2438 }}}
{{{ 4W = 2192 }}}
{{{ W = 548 }}}
{{{ L = 548 + 123 }}}
{{{ L = 671 }}}
548’ by 671’
————————
Check:
{{{ P = 2*671 + 2*548 }}}
{{{ P = 1342 + 1096 }}}
{{{ P = 2438 }}}
OK
