Length of diagonals of a rhombus
A
B
C
D
are
16
c

and
12
c
m
. Find the side and perimeter of the rhombus.

Solution
Let
p
a
n
d
q
be the diagonals and
a
be the side of rhombus,
p
=
16
c
m
,
q
=
12
c
m
As we know in a rhombus, each side is of same length and side can be calculated as below when lengths of diagonal are given-
a
=
√
