Find the area A of the polygon with the given vertices:)

Hey there! I'm happy to help!

We see that points A and B are on the same horizontal line, and and they are 10 units apart. C and D are on their own horizontal line and they are also 10 apart. This means that this is a square, so we multiply one side by itself

10²=100

The area is 100 square units.

Have a wonderful day! :D

55.7 m2

Step-by-step explanation:Step 1  

                                             3x2=6

                                             3x9.9=29.7

                                             10x2=20

                                              Step 2

                                               6+29.7+20=55.7
