The formula for the perimeter is 2L+2W= p; as L= length and W=width.
We already have 2/3 of the formula covered, we just need to figure out the length.
2L+2(6)= 26
2L+12=26; Now lets subtract 12 from both sides so we can get L by itself.
2L=14
L=7
The length is 7, and we can check to see if we're right.
6+6+7+7=26
12+ 14=26
26=26
The length of the rectangle is 7 inches.
