Area of a kite. Working out the area of a kite shape.

To find the area of the kite all you need to know is the two diagonal lengths (a diagonal is a line that goes from 1 corner to another corner).

All you need to do is multiply the two diagonal lengths together and halve your answer.

You can summarise this with the following formula:

A = hw/2

(A is the area of the kite, h is the length or diagonal 1, and w is the width or diagonal 2).

Let’s take a look at a couple of examples of working out the area of a kite.

Example 1

Work out the area of this kite.

The diagonals of the kite are as follows:

h = 8 cm

w = 6 cm

All you need to do now is substitute these numbers into the formula for the area of a kite.

A = hw/2

A = 8 × 6 /2

A = 24 cm²

So the area of the kite is 24 cm²

Example 2

Work out the area of this kite. Round your answer off to 1 decimal place.

The diagonals of the kite are as follows:

h = 7.39 m

w = 4.75 m

All you need to do now is substitute these numbers into the formula for the area of a kite.

A = hw/2

A = 7.39 × 4.75 /2

A = 17.6 m² rounded to 1 decimal place.

So the area of the kite is 17.6 m²
