$perimeter = 2(length + width) \\ = 2((2 {x}^{2} + 9x - 7) + ( {x}^{2} - 9) )\\ = 2(2 {x}^{2} + 9x - 16) \\ = (4 {x}^{2} + 18x - 32) \: units$

width = x +5length = 3x +2area = 3x² +17x +10

Step-by-step explanation:

a. width = x +5 . . . . . . 5 ft more than the size of the tomato patch

length = 3x +2 . . . . . 2 ft more than 3 times the size of the tomato patch

b. area = length × width = (3x +2)(x +5)

area = 3x² +17x +10
