#### Solution

Mark the distance 9.3 from a fixed point A on a given line to obtain a point B such that

AB = 9.3 units. From B mark a distance of 1 unit and mark the new point as C. Find the mid-point of AC and mark that point as O. Draw a semi-circle with centre O and radius OC. Draw a line perpendicular to AC passing through B and intersecting the semi-circle at D. Then `BD = sqrt9.3" ."`
