Answer:
Explanation:
Note that the first 2 points have the same y-coordinate (5) which means that the line joining them is horizontal so its length is -1 - (-4) = 3 units.
The line joining the last 2 points is also horizontal and its length is
4 - (-4) = 8 units.
If we draw the polygon on the coordinate plane we see that the polygon is a trapezoid so its area
= 1/2 h (a + b) where a and b are the above 2 lines and h is the distance between these lines.
h = 5 - (-3) = 8
so the area = 1/2 * 8(3 + 8)
= 44 unit^2.
