perimeter = 2 x (length + width)
⇒ length + width = perimeter ÷ 2
⇒ length = (perimeter ÷ 2) - width
So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it.
IF you meant "What is the length..." then:
length = perimeter ÷ 2 - width
= 40 ÷ 2 - 2 in
= 20 - 2 in
= 18 in
