Answer:
402 mi²
Step-by-step explanation:
Extending the vertical segments divides the figure into 3 rectangles:
left: 22 mi by 12 mi
center: 13 mi by 6 mi
right: 20 mi by 3 mi
The area of each rectangle is the product of its length and width. The total area is the sum of the areas of the three rectangles:
total area = (22·12 +13·6 +20·3) mi² = (264 +78 +60) mi² = 402 mi²
