Answer:

14 sq. units

Step-by-step explanation:

We know that :

  • Area (Δ) = 1/2 x Base x Height

Base

  • Take the difference between the lowest x-value and highest x-value
  • -4 + 8 = 4 units

Height

  • Take the difference between the lowest y-value and highest y-value
  • 9 - 2 = 7 units

Area

  • 1/2 x 4 x 7
  • 28/2
  • 14 sq. units
