Answer:

Total area = 70 sq. km

Step-by-step explanation:

We can make it into 2 parts.

Down part)

It is rectangle ;length = 14 km

width = 3 km

Area = length * width

         = 14 * 3 = 42 sq. km

Above part)  It is rectangle

length = 7 km

width = 4km

Area = length * width

          = 7 * 4

           = 28 sq. km

Total area = 42 + 28 = 70 sq. km
