Final answer:
The area of a triangle with a base of 3 yards and a height of 7 yards is calculated using the formula (1/2 × base × height), which results in an area of 10.5 square yards.
Step-by-step explanation:
To find the area of a triangle with a base of 3 yards (yd) and height of 7 yards (yd), you can use the formula for the area of a triangle, which is 1/2 × base × height. Plugging in our values, we would calculate the area as follows:
- Write down the formula: Area = 1/2 × base × height
- Substitute the given measurements into the formula: Area = 1/2 × 3 yd × 7 yd
- Perform the multiplication: Area = 1/2 × 21 yd²
- Calculate the final answer: Area = 10.5 yd²
Therefore, the area of the triangle is 10.5 square yards.
