use the polygon tool to draw a rectangle with a length of 4 units and a height of 2 units. one of the sides of the rectangle falls on line ef, and the rectangle has a vertex of e.
each segment on the grid represents 1 unit.

To draw a rectangle with a length of 4 units and a height of 2 units, you just have to begin at point E.

Starts on point E and draw a segment 2 units long, because the problem states that the height is 2 units, and heights are always vertical.Then, after drawing the 2 units, draw a segment 4 units long to the right, where is the blank space.After having that horizontal 4-units segment, draw a segment upwards 2 units long, at that point you must be at the same height than point E.Finally, draw a 4-units segment to the left, and you will be back on point E, closing up the rectangle.

The rectangle must be like the one attached.
