All you need to do is go up to the letter and then from where the letter sits. look at the number to left and put it as the bottom number first and the number towards the left at the end like this ex: (8,2)
You know each side is 9 meters long, meaning it’s a square. To find perimeter, add up all the sides aka. 9+9+9+9=36. To find the area, multiply one side by the other aka. 9x9 = 81.
