Answer:

See below

Step-by-step explanation:

  • Note: See https://brainly.com/question/17697603 for the plotting part

Points given

  • R (7, -1), A(3,-6), B(-3,-6), E(-5, 4)

Part A

Distance formula:

  • d= √(y2-y1)²+ (x2-x1)²

Side lengths:

  • AB= 3- (-3) = 6 units
  • AR = √(7 -3)² + (-1+6)²= √4²+5²= √41= 6.40 units
  • ER = √(7+5)²+(-1-4)²= √12²+5²= √169= 13 units
  • BE = √(-3+5)²+(-6-4)² = √8²+10²= √164 = 12.80 units

Part B

Perimeter is the sum of length of the sides

  • P = 6 + 6.4 + 13 + 12.8 = 38.2 units
