Mr. Barth is painting an arrow on the school parking lot. He plots the arrow on the coordinate plane as shown below. What is the area of the arrow he is painting?


A
60 square units
B
75 square units
C
70 square units
D
65 square units

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
