Answer: equation for length 34- (6.5 times 2) that whole thing divided by 2
Step-by-step explanation:
You know the width and a rectangle has 2 PAIRS of equal sides so if you know the width you just have to multiply that by 2 [ to account 4 the other side with the same length] and subtract that from the perimeter! Then you divide that answer by 2 to get what one side's length is!
