Area of Triangles and Parallelograms

The video tutorial explains how to find the area of a parallelogram by transforming it into a rectangle, using the formula base times height. It then demonstrates how to calculate the area of a triangle by forming a parallelogram with two congruent triangles, using the formula base times height divided by 2. The tutorial emphasizes understanding the relationship between these shapes and their areas.

What transformation can be used to find the area of a parallelogram?

• Cutting and sliding to form a rectangle

• Folding to form a triangle

How do the base and height of a parallelogram relate to its area?

• They are added together

• They are subtracted

• They are divided

• They are multiplied together

What is the area of a parallelogram with a base of 14 cm and height of 10 cm?

• 100 cm squared

• 24 cm squared

• 140 cm squared
