Area of parallelogram

समांतर चतुर्भुज का क्षेत्रफल

In this Class 9 Mathematics topic from “Area and Perimeter,” students learn to find the area of a parallelogram using the formula base × corresponding perpendicular height. They explore why changing the slant does not alter the area when the base and height remain fixed, distinguish the perpendicular height from the sloping side, and solve numerical and word problems involving units and conversions. The topic builds a strong foundation for comparing areas of related plane figures.
