Draw a line segment of length 7.3 cm using a ruler.

Answer:

                In order to construct a line segment of length 7.3 cm using a ruler, we use the following steps: Step I Mark a point A on the paper and place the ruler, so that zero mark of the ruler is at A. Step II Mark with a pencil a point B against the mark on the ruler which indicates 7.3 cm. Step III Join points A and B by moving the tip of the pencil against the straight edge of the ruler. The line segment AB, so obtained is the required line segment of length 7.3 cm.
