4. The diagonals are perpendicular to each other and one of the diagonals

divides the other diagonal into two equal lengths, i.e AC  BD and BE
=ED.

Based on the properties above, you can give a definition of a kite. For
example the following.

A kite is a quadrilateral whose diagonals are perpendicular to each

other and one of the diagonals divides the other diagonal into two

equal lengths.

In the words:

The area of the kite is half

The product of the diagonals.

Symbolically:

Let L be the area of the kite with the lengths of the diagonals d1 and d2,

then

L = x d1 x d2

Andi made a kite whose diagonals were 30 cm and 50 cm. What is the area

of the kite that Andi made?

Solution:

Is known : d1 = 30 and d2 = 50

Asked : Area of kite

Answer : For example the area of the kite

Andi is L cm , then
2

L =
