Answer:

14.5 cm

Step-by-step explanation:

L = 3x - 2

W = x + 3

so the perimeter is 2 lengths + 2 widths = 2(3x-2) + 2(x+3) = 6x-4 + 2x + 6

so 8x + 2 = 46

therefore 8x = 46 - 2

so 8x = 44

so x = 44/8 = 5.5

so if the length is 3x - 2

the length must be 3(5.5) -2

or 16.5 -2 which equals 14.5 centimeters
