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

To find the area of a triangle, the formula is given by:

Area = (1/2) × base × height.

In this case, the base is 260 feet, and the height is 80 feet.

Calculating the area:

Area = (1/2) × 260 × 80

= 130 × 80

= 10,400 square feet.

Thus, the area of the triangle is indeed 10,400 square feet. This shows the application of the area formula for triangles and confirms that the calculations align with standard geometric principles, leading to the conclusion that option C, 10,400 square feet, is correct.
