FAQs on Examples: Areas of Parallelograms & Triangles- 1 Video Lecture - Class 7

1. What is the formula to calculate the area of a parallelogram?

Ans. The formula to calculate the area of a parallelogram is A = base x height, where the base is the length of one of the parallel sides and the height is the perpendicular distance between the parallel sides.

2. How do you find the area of a triangle?

Ans. The area of a triangle can be calculated using the formula A = 1/2 x base x height, where the base is the length of the triangle's base and the height is the perpendicular distance from the base to the opposite vertex.

3. What are the similarities between the formulas for calculating the area of a parallelogram and a triangle?

Ans. The formulas for calculating the area of a parallelogram and a triangle both involve multiplying a base length by a corresponding height. In both cases, the base length represents the length of a side, and the height represents the perpendicular distance to the base.

4. Can the area of a parallelogram or triangle be negative?

Ans. No, the area of a parallelogram or triangle cannot be negative. Area is a measure of the amount of space enclosed by a shape, and it is always a positive value. If the calculated area turns out to be negative, it means that the base and height values used in the formula were incorrectly assigned.

5. Is it possible for a parallelogram and a triangle to have the same area?

Ans. Yes, it is possible for a parallelogram and a triangle to have the same area. This can occur when the triangle is formed by drawing a diagonal across the parallelogram. In such cases, the base length and height of the triangle are equal to the corresponding dimensions of the parallelogram, resulting in equal areas.
