It's base is 780.5 miles in length, and the other sides are 836.25 miles and 669 miles in length. It's height is 1226.5 miles...
Is it possible to determine square miles from these numbers? If so, how many square miles in the triangle?

Not possible.
Sorry, your numbers do not make sense. The height of a triangle CANNOT be greater than the longest side.
If the base and height are correct, but the other two sides are wrong, the area would be 478,641.625 square miles.
If the three sides are correct but the height is wrong, the area would be 245,309.4 square miles.

Nice homework problem.
Draw a perpendicular line from the base to the top of the triangle. Now you have two right triangles. You know the height (1226.5 miles). You know the hypotenuses (836.25 and 669). You can therefore find the base of each triangle.
Each triangle has an area equal to the (height x base)/2. Use a calculator.

This is a simple area problem. Plug in the values of length and height in for the variables of base and height in the triangle area formula.
You can do this.

A formula does exist that can calculate the area of a triangle when all three sides are known.
This formula is attributed to Heron of Alexandria but can be traced back to Archimedes.
This formula is represented by
Area=SQRT(s(s-a)(s-b)(s-c)),
where s=(a+b+c)/2 or perimeter/2.
This formula can be used when the height is not known and it can also be used to explore relationships between the perimeter and area of a triangle.

A googly. top can not be extra advantageous than the realm. This comes below the formulation __ __ __ section = squareroot of (s x s-a x s-b x s-c) the place, a,b,c are the edges and s = (a+b+c) /2 s = 1142.875 miles. section = (1142.875 x 362.375 x 306.625 x 473.875)^a million/2 7256.37 squaremiles. clean ?
