Calculate Triangle Area: Using Height 6 and Base 3.5 Units

To solve this problem, we will determine the area of the triangle using the given base and height. Here are the steps:

• Identify the given base and height: base $= 6$, height $= 3.5$.
• Apply the formula for the area of a triangle: $\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$.
• Substitute the given values into the formula: $\text{Area} = \frac{1}{2} \times 6 \times 3.5$.
• Calculate the area: $= \frac{1}{2} \times 21 = 10.5$.

Therefore, the area of the triangle is $10.5$, which matches the correct multiple-choice option provided.
