A (12x - 6) ft
B. (12x + 6) ft
C (24x - 12) ft
D. (24x + 12) ft
If you can please show the steps​

Answer 1

C

Explanation:

Remark

The easiest way to do this is to add the two givens together and then multiply by two. Why 2? Because the formula is P = 2(L + W)

Givens

L = 8x - 2

W = 4x - 4

Solution

P = 2*(8x - 2 + 4x - 4)

P = 2*(12x - 6)

P = 24x - 12
