What is the formula for calculating the square footage of a triangle?

The appropriate formula for calculating the square footage of a triangle is based on the relationship between its base and height. The formula is derived from the general principle that the area of a triangle is equal to half of the product of its base and height. Thus, to find the area, one would multiply the base by the height and then take half of that product.

In this context, the correct option specifies that the area of a triangle is achieved by taking half of the base multiplied by the height. Therefore, the accurate representation would be "Half of the base X Height." This captures the essence of the triangle's area calculation and aligns with geometric principles.

The other options do not accurately reflect the correct method for calculating the area of a triangle, as simply multiplying the base by the height without halving it does not yield the right result, and the other options mix dimensions in ways that are not relevant to triangle area calculations.
