Solution

 

Suppose ABCD is a rhombus.
We know that the diagonals of a rhombus perpendicularly bisect each other. 

∴ ∠๐ด๐‘‚๐ต = `90^0` , ๐ด๐‘‚ = 12 ๐‘๐‘š ๐‘Ž๐‘›๐‘‘ ๐ต๐‘‚ = 5 ๐‘๐‘š
Now, In right triangle AOB
By using Pythagoras theorem we have 

 `AB^2=AO^2+BO^2` 

`=12^2+5^2` 

`=144+25` 

`=169` 

∴` AB^2=169` 

⇒ AB=13 cm 

Since, all the sides of a rhombus are equal.
Hence, AB = BC = CD = DA = 13 cm
