Rectangle Area and Perimeter Problems

The video tutorial explains how to find the perimeter of an orange rectangle within a larger rectangle with a known area of 147 square units. It begins by calculating the area of the orange rectangle by subtracting the areas of three smaller rectangles from the total area. The tutorial then determines the dimensions of each smaller rectangle using their known areas and factors. After verifying the dimensions, it calculates the perimeter of the orange rectangle. The video concludes with insights on determining the perimeter of the larger rectangle.
