Kite A B C D is shown. Lines are drawn from point A to point C and from point B to point D and intersect.

Andre45 [30]

<u>Answer:</u>

Area of kite is 30 sq units.

<u>Solution:</u>

Note: Refer the image attached

From the given,

AC = 10 ; BD = 6

Kite is a quadrilateral as it has two equal adjacent sides.

The formula for the area of quadrilateral (kite) when both the diagonals are given is

$\text { area of kite }=\frac{1}{2} \times d_{1} d_{2}$

Here AC is $d_{1}$ and BD is $d_{2}$

On substituting the given values we get

$area = \frac{1}{2}\times10\times6 = \frac{60}{2}=30 sq units$
