How do you calculate the area of a triangle ?
To calculate the area of a triangle, you can use the formula:

Area = (base * height) / 2

The base of a triangle is the length of any one of its sides, and the height is the perpendicular distance from the base to the opposite vertex. Here are the steps to calculate the area of a triangle:

1. Measure the length of the base of the triangle. Let's denote it as b.

2. Measure the height of the triangle. The height should be perpendicular to the base and can be measured as the shortest distance from the base to the opposite vertex. Let's denote it as h.

3. Plug the values of the base and height into the formula:
   Area = (b * h) / 2

4. Perform the multiplication and division to obtain the final result, which represents the area of the triangle.

It's important to ensure that the base and height are measured using the same unit (e.g., centimeters, inches) for accurate calculations.
What is the area of a triangle with a base of 5 and a height of 5?
The area of a triangle is calculated using the formula:

```
area = (1/2) * base * height
```

In this case, the base is 5 and the height is 5, so the area is:

```
area = (1/2) * 5 * 5 = 12.5
```

Therefore, the area of the triangle is **12.5**.
