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.
Perimeter= 36 Area=81 Step-by-step Perimeter means you add, so we will add all 4 sides together 9+9+9+9=36. Area means to multiply to find the inside of something to we will multiply 9x9=81. Hope this helped! :)
