Answer 2

Answer:-

The area of the rhombus is 40cm²

Step-by-step explanation:-

To Find:-

• The area of rhombus ......(?)

Solution:-

We know that,

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

Therefore, by putting the values,

$\sf{\longrightarrow \: \dfrac{1}{2} \times 8 \times 10}$

$\sf{\longrightarrow \: \dfrac{1}{ \cancel{2}} \times \cancel{8} \times 10}$

$\sf{\longrightarrow \: 1 \times 4 \times 10}$

$\bold{\longrightarrow \: 40 {cm}^{2} }$

Therefore, The area of the rhombus is 40cm²

Remember:-

• Area of Rhombus = 1/2 × d1 × d2

• Diagonal ( d2 ) = √4a² - d1²

• Diagonal ( d1 ) = √4a² - d²
