Question

what will be the are of the rhombus in cm sq if it's diagonals are integers and it's perimeter is 104cm​

Answer 1

Answer:

here is the answer

Step-by-step explanation:

Let first diagonal be d

Second diagonal be d2

Giver perimeter of a rhombus =20cm 

We know perimeter of a rhombus =4sides

Hence, side =420cm=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 ) =28=4cm

⇒(2d)2+(2d2)2=52

⇒(28)2+(2d2)2=25

⇒42+(2d2)2=25

⇒(2d2)2=25−16

⇒(2d2)2
