Drawing a rectangle given its side lengths

The video tutorial demonstrates how to draw a rectangle using geometric tools like a ruler, set square, and pencil. The task involves drawing a rectangle named XYZL with specified dimensions of 6 cm in length and 4 cm in width. The process includes drawing the first line XY, then perpendicular lines XL and YZ, and finally completing the rectangle by drawing line ZL.
