The perimeter is just the total length of the sides so 5 x 6 = 30 inches.
It is 2*(9+5) = 2*14 = 28 inches.
Half perimeter = 109. Subtract 87 and half the answer 22/2 = 11, this is the width. Add on the 87 giving 98, this is the length.
Do-it-in-your-head method:Length + width is half the perimeter, ie 76 inches;76 - 36 = 40;Half of 40 is 20: this is the width;20 + 36 = 56: this is the length.Job done.
If the perimeter is already measured in inches, there is nothing to convert. There are 18 inches in a perimeter of 18 inches.
38 x 44
Length + width = half perimeter = 100". Length is 98", width is 2"

I believe your thinking circumference. Perimeter refers to rectangular shapes. The circumference of an average Saab 9 3 = 53.4 inches, with an average diameter of 17 inches.
Half perimeter = 109. Subtract 87 and half the answer 22/2 = 11, this is the width. Add on the 87 giving 98, this is the length.

208=(2)x + 2(x+30)
Length + width = half of perimeter = 37 in. 37 - 9 = 28, half of 28 = 14 which is the width, and the length is 23
Do-it-in-your-head method: 1. Length + width is half the perimeter ie 116 in 2. 116 minus 68 is 48, half of 48 is 24 which is the width, making the length 92 in
