Question

3. The diagonals of a rhombus are 12 cm and 8.5 cm. Find its area.
​

Answer 1

Answer :-

• The area of rhombus is 51cm².

Step-by-step explanation :

To Find :-

• The area of rhombus

Solution :-

Given that,

• The two diagonals of rhombus are 12cm and 8.5 cm

As we know that,

Area of rhombus = 1/2 × d1 × d2,

Where,

• d1 = length of shorter diagonal
• d2 = length of longer diagonal

=> Area = 1/2 × d1 × d2

=> Area = 1/2 × 12 × 8.5

=> Area = 1 × 6 × 8.5

=> Area = 6 × 8.5

=> Area = 51

Therefore, The area of rhombus is 51cm².

More Information :-

Some more information related to area of rhombus :-

Area = 1/2 × d₁ × d₂ ... when two diagonals are given.

Area = base × height ... when base and height is given.

Area = b² × sin(a) ..by using trinogeometry

Answer 2

Answer:

51

Step-by-step explanation:

area of rhombus when diagonals are given is

A=(d1*d2)/2

A=(12*8.5)/2

A=51
