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
