Select any number B. Draw two parallel lines that are B units apart.
Calculate 18/B and mark out segments of length 18/B on the two lines. They can be anywhere along the entire [infinite] lengths of the lines, though obviously, it is easier to work with them if there are reasonably near each other.
Join together the left ends of the two segments; join together the right ends. These parallelograms will have areas of 18 units.
You can (1) select just one segment on one of the parallel lines and three on the other, or (2) select three pair of segments on the two parallel lines or (3) draw a fresh set of parallel lines for each parallelogram.

Can two parallelograms have the same perimeter but different areas?
yes, for example: a 4 by 5 rectangle has an area of 20 and a perimeter of 18 a 2 by 7 rectangle has an area of 14 and a perimeter of 18 they both have a perimeter of 18
How do you draw 3 different parallelograms with 18 square units?
There are infinitely many possible answers.Select any number b which is greater than sqrt(18) = 3*sqrt(2).Let h =18/bDraw a line, XY, of length b.Draw another line, parallel to the first, which is at a perpendicular distance h from the first.Select any point W on the second line and mark W which is b units from Z.Then the parallelogram WXYZ (or ZXYW) will have an area of 18 square units.The number b can be chosen in infinitely many ways. The point Z can be selected in infinitely many ways and so the number of possible parallelograms is infinite.
