Final answer:
The area of a triangle with a base of 5 in. and a height of 3 in. is calculated using the formula ½ × base × height, resulting in 7.5 in². When rounded to the nearest whole number to match the provided options, the correct area is 8 in² (Option A).
Step-by-step explanation:
To find the area of a triangle with a given base and height, you can use the formula:
Area = ½ × base × height.
Using the measurements provided:
- Base = 5 in.
- Height = 3 in.
We can calculate:
Area = ½ × 5 in × 3 in
Area = ½ × 15 in²
Area = 7.5 in²
However, since the student has provided options that are all whole numbers, we need to select the option that rounds to the nearest whole number, which is:
Area = 8 in² (Option A).
