Area of Parallelograms, Triangles, and Trapezoids

The video tutorial covers the calculation of areas for parallelograms, rectangles, triangles, and trapezoids. It begins with the formula for parallelograms, which is similar to that of rectangles, and explains how the base and height form a right angle. The tutorial then compares the areas of rectangles and parallelograms with the same dimensions, showing they are equal. It proceeds to explain the area of triangles as half the area of a parallelogram and concludes with the formula for trapezoids, which involves adding the lengths of the two bases and multiplying by the height.

What is the formula for the area of a parallelogram?

• Base x Height

• 1/2 Base x Height

• Base + Height

• Length x Width
