FAQs on Areas of Parallelograms and Triangles Class 9 Notes CBSE Maths Chapter 9 [Free PDF Download]

1. How do you find the area of a parallelogram without height?

If the slant height and angle between the slant height and the base are known, we may use trigonometry, sine, to figure out the height. Other than that if we know the small segment forming the right triangle and the slanting height, we can make use of the Pythagorean theorem.

2. What is the formula for finding an area of the parallelogram?

As we know, the opposite sides are equal in length and the opposite angles are also equal in height. So to figure out the area of the parallelogram, we’re going to multiply the base by the height. Formula A = b * h. Here, b is the base, h is the height, and * is the multiplication.

3. Is the area of a rectangle and parallelogram the same?

As you already know, the parallelogram and the rectangle are made of the same parts and have the same area automatically. In addition, we also note they have the exact same length and height as the base.
