Answer:
444,523.45 square miles (2 d.p.)
Explanation:
To find the area of a triangle formed by the locations of Miami, Bermuda, and San Juan, use Heron's formula.

Label the three sides of the triangle as 'a', 'b', and 'c', where 'a' is the distance from Miami to Bermuda (1042 miles), 'b' is the distance from Bermuda to San Juan (965 miles), and 'c' is the distance from San Juan to Miami (1038 miles):
- a = 1042 miles
- b = 965 miles
- c = 1038 miles
To find the half perimeter, s, half the sum of the three side lengths:

Substitute the values of a, b, c and s into Heron's formula and solve for area, A:

Therefore, the area of the triangle formed by the three locations is 444,523.45 square miles, to two decimal places.
