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
