Question

length of the diagonal of a rhombus are 18 cm and 30 cm respectively. find the side of the Rhombus

Answer 1

Solution :

Given -

Lenght of the diagonals = 18 cm and 30 cm respectively.

To find its side :-

Firstly , we will divide the diagonal by 1/2 that results = 9 cm and 15 cm.

Now

Let the Side be 'H'

We know that ,

➨ (H)² - (d1)² + (d2)²

➨ (H)² = (9)² + (15)²

➨ (H)² = 81 + 225

➨ (H)² = 306

➨  H = √306 = 17.49 ( approx )

➨  H = 17.49 cm

Hence ,

The side of the Rhombus = 17.49 cm
