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 ) =
