Step-by-step explanation:
Since an interior angle is 150 degrees, its adjacent exterior angle is 30 degrees. Exterior angles of any polygon always add up to 360 degrees. With the polygon being regular, we can just divide 360 by 30 to get 12 sides.
The length of the side joining points (-3, -1) and (1, 3) is given by
The length of the side joining points (1, 3) and (3, 1) is given by
The area of a rectangle is given by length times width.
Thus, the area of the given rectangle is given by
50 miles since 1 inch equals 10 miles and there's 5 inches that means 5x10=50
