Step-by-step explanation:

Let first diagonal be d

Second diagonal be d

2

Giver perimeter of a rhombus =20cm

We know perimeter of a rhombus =4 sides

Hence, side =

4

20

cm=5cm

Now, we know that the diagonals of a rhombus bisect each other at right angles (90°)

Hence, a right angled triangle can be visualized with side as hypotenuse.

Diagonal length =8cm

Half the length ( since diagonal bisect each other ) =

8

=4cm
