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
