Answer:

Step-by-step explanation:

Hello There!

The polygon shown below is a kite

We can calculate the area of a kite using this formula

[tex]A=\frac{pq}{2}[/tex]

where p and q = the diagonals

The diagonals of the shown kite are 12 ( found by adding 10 and 2) and 12 ( found by adding 6 and 6 )

So having found the diagonals we plug them into formula

[tex]A=\frac{12*12}{2} \\12*12=144\\\frac{144}{2} =72[/tex]

so we can conclude that the area of the polygon is 72

Find the area of each sector.
