Question

6. Find the area of a rhombus whose side is 5 cm and whose altitude is 4.8 cm. If one of the diagonals is 8 cm long, find the length of the other diagonal.

Answer 1

Answer:

Question :-

Find the area of a rhombus whose side is 5 cm and whose altitude is 4.8 cm. If one of the diagonals is 8 cm long, find the length of the other diagonal.

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 2

Answer:

u can calculate the area, bcs rhombus has all sides are same. its area is 1/2×d1+d2 but if we don't know diagonals then use pythagoreas theorem.

Step-by-step explanation:

u dont know this side so, using pthagoreas theorem,

AC²= AD²+DC²

and further calculation....
