Question

The area of a rhombus whose diagonals are of length 8 cm and 5 cm is …………….. . ​

Answer 1

Answer:

the area of the given rhombus is 20 cm²

Step-by-step explanation:

We know that area of rhombus = 1/2d1×d2, where

d1 and d2 are diagonal.

Area of the given rhombus 

=1/2×8×5cm ²

=20cm²

Hence, the area of the given rhombus is 

=20cm²

Answer 2

Answer:

Area of rhombus is $20\ cm ^{2}$ .

Step-by-step explanation:

To find : area of a rhombus

Given :  length of diagonals of rhombus are  8 cm and 5 cm  .

Solution :

• As per given data we know that  length of diagonals of rhombus are  8 cm and 5 cm   .
• Area of rhombus is equal to half the of the length of diagonals.  
• $d_{1}= 8\ cm$ and $d_{2} = 5\ cm$ .
• Area of rhombus = $\frac{1}{2} ( d_{1} \times d_{2} )$  

                                     $= \frac{1}{2}\times ( 8\times 5) \\\\ = \frac{1}{2}\times 40 \\\\ = 20\ cm^{2}$
