Class 9 Maths chapter 9 solutions pdf has a number of questions on area of triangle and area of parallelogram. Practice the solutions as many times as possible to master the chapter!

Area of Triangle:

A triangle has three sides which are joined to each other. A triangle in which of the angle is 90 degrees then it is called as right-angled triangle.

The area of a triangle can be given as the product of half the base and height. It can be represented as

Area= ½ b*h

Where b is base and h is height

There are different methods with which area can be calculated provided either base and height, length of the sides using Herons; formula, side-angle-side, equilateral triangle, two vectors from one vertex, etc, is given

Area of Parallelogram:

A parallelogram is a geometrical shape in which two sides of the quadrilateral are parallel to each other. The parallel lines are equal in length and the opposite angles of a parallelogram are equal to each other. Parallelogram is a flat shape is a flat shaped object. In a parallelogram opposite sides and the opposite angles are congruent to each other. The consecutive angles are supplementary. The area of a parallelogram can be given by the formula

A = b*h

A: Area of the parallelogram

b: base

h: height
