Answer:
The area of the green polygon is 81.
The area of the yellow polygon is 3.
Step-by-step explanation:
To get the green polygon, simply multiply 9 by 9. (The sides)
To get the yellow polygon, first you have to find the height. We know that the side of the green polygon is 9, so you have to do 9-7 to find the height of the triangle. That is 2
Then to find the area, use the equation: [tex]\frac{h_{b} b}{2}[/tex] . The h would be 2 and b would be 3.
The answer is 3.
