Answer:
A= 10
Step-by-step explanation:
use the distance formula [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] to find the side lengths of the polygon
[tex]NP=\sqrt{(3+2)^2+(1-1)^2}=5\\PQ= \sqrt{(3-3)^2+(1+1)^2} =2\\QR= \sqrt{(-2-3)^2+(-1+1)^2} =5\\RN= \sqrt{(-2+2)^2+(-1-1)^2}=2[/tex]
next, since the area is just length x width you multiply 5 x 2 =10
