Answer:
2400 miles²
Step-by-step explanation:
Given that:
Area off the coast is rectangular ;
Dimension of location :40 miles by 66 miles
The area of the location will be : the area of a rectangle ;
The area of a rectangle = Length * width
Area = 40 miles * 60 miles
Area = 2400 miles²
It's 21 square units. If you map it on a complex plane (x-axis is real numbers, y-axis is imaginary numbers) you'll see that the sides of the rectangle is 3 and 7 which multiply to 21.
What are the numbers for the other ones?
