Final answer:
To calculate the area of the triangle with a base length of 19.2 and an altitude of 6.4, we use the formula ½ × base × height, resulting in an area of 61.44 square units.
Step-by-step explanation:
The area of a triangle is given by the formula ½ × base × height. To find the area of a triangle with a base of 19.2 and an altitude of 6.4, we simply plug these values into the formula:
Area = ½ × 19.2 × 6.4
Area = 9.6 × 6.4
Area = 61.44
Therefore, the area of the triangle is 61.44 square units, rounded to two decimal places as needed.
