FAQs on Ex-15.1, Areas Of Parallelograms And Triangles, Class 9, Maths RD Sharma Solutions - RD Sharma Solutions for Class 9 Mathematics

1. What is the formula to find the area of a parallelogram?
Ans. The formula to find the area of a parallelogram is given as base multiplied by the height, i.e., Area = base × height.
2. How do you find the height of a parallelogram if the base and area are given?
Ans. To find the height of a parallelogram, you can rearrange the formula for the area of a parallelogram as height = Area / base.
3. What is the difference between a parallelogram and a triangle?
Ans. A parallelogram is a four-sided polygon with opposite sides that are parallel and equal in length, while a triangle is a three-sided polygon. Another difference is that a parallelogram has two pairs of opposite equal angles, whereas a triangle may have different types of angles.
4. Can a parallelogram have a right angle?
Ans. Yes, a parallelogram can have a right angle. If one of the angles in a parallelogram is a right angle, then the parallelogram is called a rectangle.
5. How do you find the area of a triangle?
Ans. The formula to find the area of a triangle is given as half of the product of the base and the height, i.e., Area = (1/2) × base × height.
