Parallelogram Area
Learning Objective
I can calculate the area of parallelograms by composing rectangles.
Key Concepts
The area of a parallelogram can be found by multiplying the base by the height.
The height of a parallelogram is the perpendicular distance between the base and its opposite side.
A parallelogram can be divided into two congruent triangles, and its area is twice the area of one of these triangles.
