How do you calculate the area of a triangle?

The area of a triangle is calculated using the formula (1/2) x Base x Height. This formula is derived from the concept that a triangle is essentially half of a rectangle when drawn with the same base and height. In this context, the base refers to the length of one side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. By multiplying the base by the height, you calculate the area of the rectangle that could be formed. Since a triangle occupies half of that rectangle, we then multiply the result by 1/2, leading us to the final formula.

The formula highlights the importance of both the base and the height in determining the area, emphasizing that both dimensions must be considered to arrive at the correct measurement of space within the triangle.
