Separate the complex figure below into two rectangles to find the area. Use the formula of a rectangle which is Area = l × w. Then do the same with the other divided piece you cut. Add the sum of both areas and that will be your Area. For the perimeter, add all the numbers up and that's all. Hope it help :D
