To calculate the area of a triangle when you know its base and height, you can use the following formula:
\[
\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}
\]
Where:
- The "base" is the length of the base of the triangle.
- The "height" is the perpendicular height from the base to the opposite vertex.
Simply multiply the base and height together and then divide by 2 to get the area.
For example, if the base of the triangle is 5 units and the height is 4 units, the area would be:
\[
\text{Area} = \frac{1}{2} \times 5 \times 4 = \frac{20}{2} = 10 \text{ square units}
\]
\[
\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}
\]
Where:
- The "base" is the length of the base of the triangle.
- The "height" is the perpendicular height from the base to the opposite vertex.
Simply multiply the base and height together and then divide by 2 to get the area.
For example, if the base of the triangle is 5 units and the height is 4 units, the area would be:
\[
\text{Area} = \frac{1}{2} \times 5 \times 4 = \frac{20}{2} = 10 \text{ square units}
