Question

ABCD is a parallelogram, AB = 14 cm, BC = 18 cm and AC = 16 cm. Find the
length of the other diagonal? /

Answer 1

Answer:

Answer is 28cm.

Step-by-step explanation:

Let the meeting point be X.

Try to use appollonius theoram in triangle ABC :-

ABsquare + BCsquare = 2(BXsquare + AXsquare.)

196+324=2(BXsquare + 64)

BX=14cm.

So full diagonal BD = 28cm.
