Jenny Bird · Answer 1

perimeter = length + length + width + width

P = 2L + 2W

2L + 2W = P

2L + 2 (6.5) = 34

2L + 13 = 34

If all you need is the equation, then the answer is the line just above.

If you need to find the length, then we solve the equation for L as shown below.

2L = 21

L = 10.5

Answer: The length is 10.5 units.
