Question

7. In a rhombus if d1 = 18 cm, d2 = 12
*
cm, its area will be
sq units​

Answer 1

Answer:

area of rhombus=1/2×(sum of its diagonals)

=1/2×(12+18)

=1/2×30

15cm^2

Answer 2

Given :

• Diagonals of Rhombus = 18 cm and 12 cm.

To Find :

• Area of Rhombus .

Solution :

$\longmapsto\tt{{d}_{1}=18\:cm}$

$\longmapsto\tt{{d}_{2}=12\:cm}$

Using Formula :

$\longmapsto\tt\boxed{Area\:of\:Rhombus=\dfrac{1}{2}\times{{d}_{1}}\times{{d}_{2}}}$

Putting Values :

$\longmapsto\tt{\dfrac{1}{{\cancel{2}}}\times{{\cancel{18}}}\times{12}}$

$\longmapsto\tt{9\times{12}}$

$\longmapsto\tt\bf{108\:{cm}^{2}}$

So , The Area of Rhombus is 108 cm² ...
