From above figure given measurements are,

12 mi, 5 mi, 9 mi, 5 mi, 3 mi, 3 mi, 6 mi, 3 mi and 5 mi

5 - 3 = 2 mi

9 + 3 = 12 mi

5 - 2 = 3 mi

5 + 3 = 8 mi

12 mi - (3 + 6) mi

12 - 9 = 3 mi

 

here we using formulas:

Area of right triangle = 1/2 * base * height and, Area of rectangle = length * width

Here Total area of the figure 

= Area of triangle + Area of rectangle + Area of rectangle + Area of rectangle + Area of triangle

= 1/2 * 12 * 8 + 9 * 3 + 9 * 2 + 12 * 3 + 1/2 * 3 * 3

= 48 + 27 + 18 + 36 + 9/2 

= 129 + 4.5

= 133.5

Total area of the figure = 133.5 mi2

Divide it into triangles and rectangles and add the area of those up
