Area of a Kite

Consider the area of the following kite.

Diagonals of a kite cut one another at right angles as shown by diagonal AC bisecting diagonal BD.

Example 7

Find the area of the following kite.

Solution:

So, the area of the kite is 176 cm².

Remember:

• Two pairs of adjacent sides of a kite are equal and one pair of opposite angles are equal.
• The diagonals intersect each other at right angles.
• One diagonal is bisected by the other.
• The area of a kite is given by the following formula where x and y are the lengths of the kite's diagonals:
