Four parallel lines through it.
Select any one side and divide its length into 5 equal parts. Draw lines that are parallel to the adjacent side to the opposite side. This will divide the rectangle into 5 equal strips.
Eight of them.
Divide each side into three equal parts. Then join the division marks on opposite sides with straight lines parallel to the other side(s).
Eight twelfths is equal to two thirds because when you divide both top and bottom by 4, you are left with 2/3.
When dividing one of for having one line parallel to one another.
Draw 2 parallel lines which will result in 3 equal rectangles within the same square.
You need to divide 1600 / 8.
