A. 13 feet
B. 25 feet
C. 26 feet
D. 38 feet

Answer 1

13 i think I’m not sure though I did it on my head lol

Answer 2

Hi! The correct awnser is 13

Explication:

The equation for Perimeter is simply 2L + 2W = P or (2 * Lenth) + (2 * Width) = p

you can also think of it as L + L + W + W. To solve equation this you do:

12 + 12 + 2L = 50 {you could also do (2 * 12) + 2L = 50}

24 + 2L= 50

(Now minus 24 from both sides of the equation)

2L = 26

(Divide 2 from both sides)

L = 13


I hope this helps! If you have any more questions about how to solve these kinds of problems, just reply to this! Good luck!
