I do not need "the given area" or a system of equations.
I do not even need to write an equation to see that

The equation I would write (if someone asked for one) is
where is the width in cm.
Of course, length is (6 more than 4 times the width).
Maybe the system of equations you ate expected to write is
,
with L and W being length and with respectively.
To solve,
you would substitute for L in
to get ,
,
,
,
,
, and
.
Then, substituting for W in ,
you would find
, a,d .
