Answer:
10 +2√109
Step-by-step explanation:
The short sides are vertical, so their length is the difference of the y-coordinates: 5.
The length of the long sides can be found from the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((5 -(-5))² +(-7 -(-4))²) = √(10² +(-3)²) = √109
There are two short sides and two long sides, so the perimeter is ...
P = 2(5 +√109)
P = 10 +2√109
