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
