Answer» Step-by-step explanation:
Answered Diagonals of a rhombus bisect each other at RIGHT angles. Let ABCD be the rhombus, Diagonal AC= 16 cm and side AB = 10 cm. In right triangle AOB, AB = 10 cm, AO = 8 cm By Pythagoras theorem, AB2 = AO2 + BO2 (10)2 = (8)2 + BO2 BO2 = (10)2 – (8)2 BO = 6 cm Diagonal BD = 2 x 6 = 12 cm Hence LENGTH of other diagonal = 12 cm; Area of rhombus = 96 cm2 Mark my answer as brainliest.
