Answer:

  • 20.6

Step-by-step explanation:

Coordinates given:

  • D(-3,2)
  • E(4,2)
  • F(4,-3)

Plotted, these points give a right triangle with hypotenuse DF

  • Distance DE = 4 - (-3) = 7
  • Distance EF = 2 - (-3) = 5
  • Distance DF = √(7²+5²) = √84 = 8.6

Perimeter

  • P = 7 + 5 + 8.6 = 20.6
