Video Summary

The problem involves six rectangles with given areas, where the top left rectangle's height is 6 cm. To find the height of the bottom right rectangle, we assign variables to unknown lengths and solve equations based on the given areas. By substituting and solving for each, we determine the variables: A = 3, B = 4, C = 4, D = 2, E = 8, F = 6. Finally, calculating for the bottom right rectangle with area 30, we find the height by dividing the area by the base (6 cm), giving us a height of 5 cm. The answer is 5 cm.
