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.

Unfortunately, as a text-based AI, I am unable to draw a visual representation. However, I can describe the steps you can follow to draw the rectangle using the Polygon tool:

1. Open the Polygon tool in your chosen drawing software or platform.
2. Click on point E, which will be one of the vertices of the rectangle.
3. Move the cursor horizontally to the right, keeping the length of 4 units in mind.
4. Click on the grid where the side of length 4 units ends. This will be point F.
5. Move the cursor vertically upwards, keeping the height of 2 units in mind.
6. Click on the grid where the height of 2 units ends. This will be point G.
7. Move the cursor horizontally towards the left until it aligns with point E.
8. Click on point E to close the rectangle.

Once you follow these steps, you should have successfully drawn a rectangle with a length of 4 units and a height of 2 units, where one of the sides falls on line EF, and the rectangle has a vertex of E.
