FAQs on Examples: Area of Parallelograms Video Lecture - Crash Course: Class 9

1. What is the formula to find the area of a parallelogram?
Ans. The formula to find 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 base and the opposite side.
2. How do you find the height of a parallelogram if only the base and area are given?
Ans. To find the height of a parallelogram when only the base and area are given, you can rearrange the formula for the area and solve for the height. The formula becomes height = area / base.
3. Can we use the formula for finding the area of a parallelogram if the sides are not parallel?
Ans. No, the formula for finding the area of a parallelogram only works when the opposite sides are parallel. If the sides are not parallel, the shape is not a parallelogram and a different formula or method must be used to find the area.
4. How is the area of a parallelogram related to the area of a rectangle?
Ans. The area of a parallelogram is equal to the area of a rectangle with the same base and height. This is because a parallelogram can be divided into two congruent triangles, and when these triangles are rearranged, they can form a rectangle with the same dimensions.
5. Can the area of a parallelogram be negative?
Ans. No, the area of a parallelogram cannot be negative. Area is a measure of the amount of space occupied by a shape, and it is always a positive value. If the calculations result in a negative value, it usually indicates an error in the measurements or calculations used.
