Answer:

perimeter = 40

area = 46(unit)^2

Step-by-step explanation:

Perimeter - all sides added together

  1. Find unknown sides (8-3 = 5, 12-2 = 10)
  2. Add all sides together (8+2+5+10+3+12 = 40)

Area - Length multiplied by width

  1. Divide shape into two rectangles (#1 is 2x5 and #2 is 3x12)
  2. Find individual area (rectangle #1: 2*5 = 10 / rectangle #2: 3*12 = 36)
  3. Add areas together (10+36 = 46)
  4. Finish with unit squared (46___^2)
