Solution 1: Count, which is crazy long so I am going to solution 2.
Solution 2: Calculate.
I am going to split the right part to the left part result two shapes: 8x5 and 6x15
8x5 + 6x15 = 40 + 90 = 130.
Area = 130 units^2
Perimeter: 8x2 + (6x2-5)+ (15x2-5) (Subtract 5 because the overlap area)
16 + 7 + 25 = 48
Perimeter = 48 units
