Question

(-5, 1), (-5, -4), (5, - 2), (5, -7)

Answer 1

9514 1404 393

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
