Answer: 48 square feet.
Step-by-step explanation:
So you can say 12x12 is 144. You know there are 4 sides. They will be all twelve as this is a square.
The perimiter is 12 plus 12 plus 12 plus 12 equals 48 square feet
Its 43. All triangles add to 180 so 47 + 90 = 137. then subtract 180 - 137 and get 43
