Question

Diagonals of a rhombus are 30 cm and 16cm respectively, then the length of each side of the rhombus is _________. *​

Answer 1

Answer:

Given: Diagonals AC=30cm and DB=16cm.

Since the diagonals of the rhombus bisect at right angle to each other.

Therefore, OD=

DB

=

16

=8cm

and OC=

AC

=

30

=15cm

Now, In right angle triangle DOC,

(DC)

=64+225=289

⇒DC=

289

=17cm

Perimeter of the rhombus=4× side

=4×17=68cm

Thus, the perimeter of rhombus is 68 cm.
