first draw a line of length 6.4cm and label the enda a and b
then extend it 1cm and label the end c
then bisect the line into halves
and mark the center as o
from the center of the draw a arc from a to c
now from b draw a perpendicular which meets on the arc
marke the point on arc as d
then using a compass
b as center and d as start draw an arc
the arc must meet on a-c
mark the point on ac as f
measure b - f is root 6.4
