What is the area of a triangle whose base is 260 feet and height is 80 feet?

To find the area of a triangle, you use the formula:

Area = (Base × Height) / 2.

In this case, the base of the triangle is 260 feet and the height is 80 feet. Plugging these values into the formula gives:

Area = (260 feet × 80 feet) / 2.

Calculating the product of the base and height:

260 × 80 = 20,800.

Now, dividing that by 2 to find the area:

20,800 / 2 = 10,400 square feet.

Thus, the correct answer is 10,400 square feet, which aligns with the provided answer choice. The other options represent different calculations and are not obtained by applying the area formula correctly to the dimensions given.
