Question

find the area of a rhombus whose side is 5cm and whose altitude is 4.8cm . if one of its diagonal is 8cm long find the length of other diagonal

Answer 1

Solution:-

Area of the rhombus = Side × Length of the altitude 
= 5*4.8
= 24 sq cm 
Now,
Let the length of the other diagonal = x
It is known that the area of a rhombus is half the product of its diagonals. 
∴ (1/2) × 8 × x = 24
⇒ 4x = 24
⇒ x = 6 cm
The length of the other diagonal is 6 cm.
Answer.

Answer 2

Answer: 6cm

Step-by-step explanation:

Solution:-

Area of the rhombus = Side × Length of the altitude 

= 5*4.8

= 24 sq cm 

Now,

Let the length of the other diagonal = x

It is known that the area of a rhombus is half the product of its diagonals. 

∴ (1/2) × 8 × x = 24

⇒ 4x = 24

⇒ x = 6 cm

The length of the other diagonal is 6 cm.
