Answer: Area - 17a^2 b, Perimeter - 10a^2 + 10 b
Explanation:
To find the area, we can divide the figure into 3 separate rectangles.
Then, we find the area of each separate rectangle and add them together.
Area = a^2b + a^2b + 15a^2b
Area = 17a^2 b
The perimeter is the sum of all sides
Perimeter = a^2 + b + 3a^2 + b + a^2 + 4b + 5a^2 + 4b
Perimeter = 10a^2 + 10 b
