Answer: 15 Inches

Step-by-step explanation:Remember that the Perimeter of a rectangle is the distance around it.

So,

Perimeter = Length + Width + Length + Width

or

P = 2L + 2W

If P=42 inches and W = 6 inches,

42 = 2L + 2(6)

42 = 2L + 12

30 = 2L [subtract 12 from both sides]

15 = L [divide both sides by 2]

The length (L) is 15 inches.
