FAQs on Area of triangle..... - Class 11

1. What is the formula to find the area of a triangle?

Ans. The formula to find the area of a triangle is given by the formula: Area = (base * height) / 2. Here, the base is the length of the triangle's base, and the height is the perpendicular distance from the base to the opposite vertex.

2. How do you calculate the area of a right-angled triangle?

Ans. To calculate the area of a right-angled triangle, you can use the formula: Area = (base * height) / 2. In this case, the base and height are the lengths of the two sides that form the right angle.

3. Can you find the area of a triangle if only the lengths of its sides are given?

Ans. Yes, it is possible to find the area of a triangle if the lengths of its sides are given. You can use Heron's formula, which states that the area of a triangle with sides a, b, and c is given by the formula: Area = sqrt(s * (s-a) * (s-b) * (s-c)), where s is the semi-perimeter of the triangle, calculated as s = (a + b + c) / 2.

4. How can I find the area of an equilateral triangle?

Ans. To find the area of an equilateral triangle, you can use the formula: Area = (side^2 * sqrt(3)) / 4. Here, the side represents the length of one side of the equilateral triangle.

5. Is it possible to find the area of a triangle if only the lengths of two sides and the included angle are given?

Ans. Yes, it is possible to find the area of a triangle if the lengths of two sides and the included angle are given. You can use the formula: Area = (1/2) * a * b * sin(C), where a and b are the lengths of the two sides and C is the included angle between them.
