Answer - 150
One square has an area of 25 (5x5) so 6 squares (25x6) have an area of 150.
Coordinate of A are (0,0)
Coordinates of A' are (5,2)
We can find the distance from A to A' using the distance formula:
Thus, rounded to nearest hundredth, AA' is equal to 5.39
The second one because the second one equals to 12 while all the other equal to 6
I would find the area of the shape as if it were a rectangle (5x9) and then subtract the area of two triangles (1/2x2x2.5)
