Answer:

26 inches

Step-by-step explanation:

First, subtract 18 by 70, since there will be 2 width amounts in the perimeter:

70 - 18

= 52

Then, divide this by 2, to find the length:

52/2

= 26

So, the length is 26 inches.

Answer:

Length = 26 in.

Step-by-step explanation:

Length = (P/2)-w

            = (70/2)-9

            =  35-9

            = 26
