Question 926718
Let {{{ w }}} = the width
{{{ 3w }}} = the length
Let {{{ P }}} = the perimeter
{{{ P = 2w + 2*( 3w ) }}}
{{{ P = 2w + 6w }}}
{{{ P = 8w }}}
and
{{{ P = 1260 }}}
{{{ 1260 = 8w }}}
{{{ w = 157.5 }}}
and
{{{ 3w = 472.5 }}}
-----------------
The garden is 157.5 x 472.5
check:
{{{ P = 2w + 2*( 3w ) }}}
{{{ P = 2*157.5 + 2*472.5 }}}
{{{ P = 315 + 945 }}}
{{{ P = 1260 }}}
OK
