Answer:

See below ~

Step-by-step explanation:

Finding the distance of each side length :

  • AB = √(3 - 0)² + (0 - 4)² = √9 + 16 = √25 = 5
  • BC = √(7 - 3)² + (3 - 0)² = √16 + 9 = 5
  • CD = √(4 - 7)² + (7 - 3)² = √9 + 16 = 5
  • DA = √(4 - 0)² + (7 - 4)² = √16 + 9 = 5
  • All sides are equal
  • Hence, it is a square

Perimeter :

  • 4 x side length
  • 4 x 5
  • 20 units

Area :

  • (side length)²
  • (5)²
  • 25 square units
