Final answer:
To find the area of the triangular garden with a base of 10 feet and a height of 8 feet, the formula for the area of a triangle ½ × base × height is used, resulting in an area of 40 square feet.option c is correct.
Step-by-step explanation:
To calculate the area of the triangular garden, we use the formula for the area of a triangle, which is Area = ½ × base × height. Since the base is given as 10 feet and the height as 8 feet, we plug these values into the formula:
Area = ½ × 10 ft × 8 ft
Area = ½ × 80 ft²
Area = 40 ft²
Therefore, the area of the garden is 40 square feet, which corresponds to option C.
