Question

ABCD is a parallelogram. Diagonals
AC and BD intersect at 0.
If OC = 5.5 cm and BD is 4 cm less
than AC, then what is length of OB?​

Answer 1

Answer:

When diagonal AC and BD intersect each other at point o,

then OA = OC = (1/2) AC

And OB = OD = (1/2) BD

∴ OA = 1/2 × AC = 1/2 × 12 = 6 cm

and OB = 1/2 × BD = 1/2 × 9 = 4.5 cm
