Question

If the perpendicular bisector of line segment CD intersects it at point O, 5.4 cm from C, then find the length of CD.

Answer 1

A perpendicular bisector of a line segment divides the line segment into 2 equal parts. Hence if the perpendicular bisector of line segment CD intersects it at point O, 5.4 cm from C, the length of CD is 5.4 x 2 = 10.8 cm.
