Answer: 518</h3>
Explanation:
Let's draw a vertical line to split the figure into two rectangles.
The rectangle on the left is 42 by 9, so its area is 42*9 = 378.
The rectangle on the right is 7 by 20 giving an area of 7*20 = 140.
Overall, the entire area is 378+140 = 518 square yards
This is a piecewise function & the turning point is (-4,2)
