Question

find the area of rhombus whose diagonal are 12cm and 9cm​

Answer 1

Answer:

area= 54

Step-by-step explanation:

area= (12×9)/2

= 54

Answer 2

Given:

Diagonals of rhombus are 12cm and 9cm

To find:

The area of rhombus.

Formula to be used:

Area of rhombus = $\frac{1}{2}$ × $d_1$ × $d_2$

Solution:

We can calculate the area of rhombus by using the following formula,

Area of rhombus = $\frac{1}{2}$ × $d_1$ × $d_2$

Diagonals of rhombus are 12cm and 9cm

$d_1$ = 12cm

$d_2$ = 9 cm

Therefore,

Area of rhombus = $\frac{1}{2}$ × 12 × 9

Area of rhombus = 6 × 9

Area of rhombus = 54 cm²

Final answer:

The area of rhombus is 54 cm²
