Answer :
70 square units
Step-by-step explanation:
I have plotted the points on the coordinate system and connected roughly using a red line. Image is attached.
The arrow created, consists of a TRIANGLE and a RECTANGLE. The area of the arrow would be:
Area of Arrow = Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 * base * height
Base is 12 units
Height is 7 units, so
Area of Triangle = 0.5 * 12 * 7 = 42
Now,
Area of Rectangle = length * height
Length is 7
Height is 4
Area of Rectangle = 7 * 4 = 28
Area of Arrow = 42 + 28 = 70 square units
