Question 373455
Let {{{L}}} = length
Let {{{W}}} = width
the formula for perimeter is
{{{2L + 2W}}}
given:
{{{2L + 2W = 28}}}
{{{L = 2W - 4}}}
---------------
By substitution:
{{{2*(2W - 4) + 2w = 28}}}
{{{4W - 8 + 2W = 28}}}
{{{6W = 28 + 8}}}
{{{6W = 36}}}
{{{W = 6}}}
and, since
{{{L = 2W - 4}}}
{{{L = 2*6 - 4}}}
{{{L = 8}}}
The length is 8 ft and the width is 6 ft
