Final answer:
To solve for p using the given values of L and W, substitute them into the equation P = 2L + 2W. The correct answer is p = 4z + 6 ft.
Step-by-step explanation:
To solve for p, we need to substitute the given values of L and W into the equation P = 2L + 2W. Given that L = 2z ft and W = 3 ft, we can substitute these values into the equation as follows:
P = 2(2z) + 2(3) = 4z + 6.
Therefore, the correct answer is a) p = 4z + 6 ft.
