Please help! I'm really confused :(
thank you!
The area of the polygon is the number of little squares that fit into the polygon.
We can split the polygon up like this:
area of polygon = area of rectangle + area of triangle
area of rectangle = base * height
area of rectangle = 9 * 2
area of rectangle = 18 (You can count the squares to get the same answer.)
area of triangle = (1/2) * base * height
area of triangle = (1/2) * 9 * 6
area of triangle = 27
area of polygon = area of rectangle + area of triangle
area of polygon = 18 + 27
area of polygon = 45
There are 45 square units in the polygon.
