Answer:

P = 16x - 30 units

Explanation:

Let the length and width of the rectangle be (3x - 4) & (5x - 11)


perimeter \: of \: rectangle \\ = 2(l + w) \\ = 2(3x - 4 + 5x - 11) \\ = 2(8x - 15) \\ = (16x - 30) \: units

Answer:

P = 16x - 30

Explanation:

P = 2L + 2W

P = 2(3x - 4) + 2(5x - 11)

P = 6x - 8 + 10x - 22

P = 16x - 30
