What is the formula of the kite above?

solmaris [256]

Answer:

Option D

Step-by-step explanation:

The area of a kite is expressed as $\frac{1}{2} \times \text{(Product of it's diagonals)}$ .

We are given the following:

Diagonal₁ = D1
Diagonal₂ = D2

Substitute the diagonals in the formula and simplify;

$\implies \text{Area of kite} =\dfrac{1}{2} \times \text{(D1} \times \text{D2} )}$

$\implies \text{Area of kite} =\dfrac{1}{2} \text{(D1} \times \text{D2} )} \ \ \ [\text{Option D}]$

Thus, Option D is correct.
