Calculating Area and Perimeter of Irregular Shapes

The video tutorial explains how to identify missing side lengths of a shape and calculate its perimeter and area. It begins by recognizing unlabeled sides and using parallel lines to determine their lengths. The perimeter is calculated by summing all side lengths. For the area, the shape is divided into two rectangles, and their areas are calculated and summed. The tutorial emphasizes understanding the relationship between parallel lines and using multiplication for area calculation.

What is the total length of the side that is parallel and equal to the side labeled 6 inches?

• 6 inches

• 12 inches

• 3 inches

• 9 inches
