Area of a Triangle Calculator
Use this calculator to find the area of a triangle when you know its base and height.
Area tells you how much space the triangle covers (in square units).
In the diagram, the base is b and the height is h.
Step-by-step method
- Identify what is given.
- Write the formula.
- Substitute the values and calculate the area.
Formula:
Example 1: b = 5, h = 3
Step 1 - Identify what is given.
In this problem: The given values are b = 5 and h = 3.
Step 2 - Write the formula.
In this problem: Use the triangle area formula: A = ½bh.
Step 3 - Substitute the values and calculate the area.
In this problem: Substitute b = 5 and h = 3: A = ½ × 5 × 3 = 7.5.
Final answer: A = 7.5
Example 2: b = 7.5, h = 2
Step 1 - Identify what is given.
In this problem: The given values are b = 7.5 and h = 2.
Step 2 - Write the formula.
In this problem: Use the triangle area formula: A = ½bh.
Step 3 - Substitute the values and calculate the area.
In this problem: Substitute b = 7.5 and h = 2: A = ½ × 7.5 × 2 = 7.5.
Final answer: A = 7.5
