To find the area of a triangle, you can use the formula:
Area = 1/2 × base × height
In this case, the base of the triangle is 15 meters and the height (altitude) is 12 meters. Plugging these values into the formula gives:
Area = 1/2 × 15m × 12m
Calculating this step by step:
- First, multiply the base and the height: 15m × 12m = 180m²
- Next, divide that result by 2: 1/2 × 180m² = 90m²
So, the area of the triangle is 90 square meters.
This formula works for any triangle as long as you know the base and the height, allowing you to easily calculate the area with just those two measurements.
