Question

If the diagonals of a rhombus are 12 cm and 5 cm, find the perimeter of the rhombus.

Answer 1

Answer:

26

Step-by-step explanation:

Let p=12 cm and q=5

We know perimeter of rhombus =2

p

2

+q

2

Thus perimeter of the rhombus with given diagonals = 2

12

2

+5

2

= 2

144+25

= 2

169

=2×13=26 cm

Answer 2

Answer:

26 cm

Step-by-step explanation:

The formula for Rhombus Perimeter is given by:

P = 2 x square root of ( d1^2 + d2^2)

Here d1 = 12 and d2 = 5

So,

P = 2 x square root of ( 12^2 + 5^2)

= 2 x square root of ( 144 + 25)

= 2 x square root of ( 169 )

= 2 x 13

= 26
