: Winter wheat. While finding the amount of seed needed
to plant his three square wheat fields, Hank observed that
the side of one field was 1 kilometer longer than the side
of the smallest field and that the side of the largest field

Let x = the side of the smaller field, then (x+1) = the side of the middle field and (x+3) equal the side of the largest field.
The three areas, which sum to 38 sq.km. are:
Simplify.
Subtract 38 from both sides.
Factor this trinomial.
Apply the zero product rule.
or
or Discard the negative solution as the side must be a positive value.
The area of the smallest field is sq.km.
The area of the middle field is sq.km.
The area of the largest field is sq.km.
