Answer:
1. Draw AB = 7 cm.
2. Extend AB to C such that BC = 1 cm.
3. Bisect AC to get the midpoint O and draw a semicircle with AC as the diameter with O as center.
4. Draw a perpendicular from B to intersect the semicircle at D.
5. BD=√7
6. With B as center and radius = BD, draw an arc intersecting AC at point E.
7. Mark B as the origin( value 0 ) of your new number line.
8. As BD = BE, therefore BE=√7
