Find the area of the bermuda triangle if the sides of the triangle have the approximate lengths 841 miles

Assuming an equilateral triangle of 841 miles on each side.
Each angle of the triangle must be 60 degrees, and the height of the triangle is H=841*sin(60)=841*sqrt(3)/2
B=base = 841 miles
So area = (1/2)base*height
=841*[841*sqrt(3)/2]/2
=306261.66 sq. miles.
