Jonathan is helping to design a new community park that will feature a large rectangular playground and a smaller rectangular picnic area. The playground is to be 15 meters long and 10 meters wide. The picnic area is 5 meters long and 3 meters wide. To determine the amount of fencing needed to enclose both areas, Jonathan wants to calculate the total perimeter of both the playground and the picnic area. What is the total perimeter of both areas combined?
