Answer:
Perimeter is all sides added together, while Area is one side height times length
Explanation:
Since your shape is a square all sides are equal so the equation is the same for all sides
Perimeter = 4z+3+4z+3+4z+3+4z+3 or (4z+3)4
14z+12 <= answer for perimeter
Area = (4z+3) (4z+3)
16z^2+12z+12z+9
16z^2+24z+9 <= answer for area
