How to Calculate the Area of a Triangle: Formula & Examples for Class 6
FAQs on Area of Triangles: Class 6 Maths Worksheet with Solutions
1. What is the formula for the area of a triangle for Class 6?
The formula to calculate the area of a triangle for Class 6 is Area = ½ × base × height. This fundamental formula requires two key measurements: the base (which can be any side of the triangle) and the corresponding height (the perpendicular distance from that base to the opposite vertex). For example, if a triangle's base is 10 cm and its height is 5 cm, the area would be ½ × 10 × 5 = 25 cm².
2. How do you solve area of triangle word problems for Class 6?
To solve area of triangle word problems, you should follow a simple step-by-step method to ensure accuracy. First, carefully read the problem to identify the given measurements and what you need to find. Here are the steps:
- Read and Understand: Identify the key information in the word problem.
- Find the Values: Determine the length of the base and the corresponding height from the text.
- Apply the Formula: Use the correct formula: Area = ½ × base × height.
- Calculate the Area: Substitute the values into the formula and solve the equation.
- Include Units: Always state your final answer with the appropriate square units, such as cm² or m².
3. What are the main types of triangles I need to know in Class 6?
In Class 6 Maths, triangles are primarily classified based on the length of their sides and the measure of their angles. Understanding these types is crucial for geometry.
Classification by Sides:
- Equilateral Triangle: A triangle where all three sides are of equal length.
- Isosceles Triangle: A triangle with two sides of equal length.
- Scalene Triangle: A triangle where all three sides have different lengths.
- Acute-angled Triangle: A triangle where all three angles are acute (less than 90°).
- Right-angled Triangle: A triangle that has one angle exactly equal to 90°.
- Obtuse-angled Triangle: A triangle that has one angle that is obtuse (greater than 90°).

- Familiarising you with the question patterns commonly found in school exams.
8. What is the difference between the area and perimeter of a triangle?
The area and perimeter of a triangle are two different measurements that describe its geometric properties. The area measures the space enclosed by the triangle, while the perimeter measures the distance around it.
- Area: This is the total surface covered by the triangle. It is calculated using the formula Area = ½ × base × height and is expressed in square units (e.g., cm², m²).
- Perimeter: This is the total length of the triangle's boundary. It is calculated by adding the lengths of all three sides: Perimeter = Side 1 + Side 2 + Side 3. It is expressed in linear units (e.g., cm, m).
9. How do you find the area of a right-angled triangle?
Finding the area of a right-angled triangle is very straightforward because its perpendicular sides act as its base and height. The two sides that form the 90° angle can be directly used in the area formula.
- Consider the two perpendicular sides as the base and height.
- Apply the standard formula: Area = ½ × base × height.
- This simplifies the triangle area calculation as you do not need to find a separate height measurement.
10. Why are the base and height important for calculating a triangle's area?
The base and height are essential because they represent the two perpendicular dimensions required to measure the two-dimensional space of a triangle. A triangle can be thought of as half of a parallelogram, and the area of a parallelogram is its base times its height. Therefore, the area of a triangle formula (½ × base × height) uses these two specific measurements to accurately determine the total space it occupies.
