Answer:
32
Step-by-step explanation: A=4, b=2
Top side 3b this means 3(2)=6
The bottom side measurement is the same 6
The left side 3a - b means 3(4) - 2 = 10
The right side measurement is the same as the left 10
Don't forget is a rectangle ( In a rectangle, all the angles are the same, and the opposite sides are the same length and are also parallel.)
The perimeter is the sum of all sides:
Therefore, 6 + 6 + 10 + 10 =32
