Answer:
So then the perimeter is just the sum of all of these lengths,
P= 6+4+3+5
Step-by-step explanation:
From (1,3) to (7,3) is 6 units.
From (7,3) to (7,7) is 4 units.
From (7,7) to (4,7) is 3 units.
You need to calculate the distance from (4,7) to (1,3)
Using the distance formula,
D² = (×1 - ×2)² + (y1 - y2)²
D² = (4 - 1)² + (7 - 3)²
D² = 9 + 16
D² = 25
D² = 5
