Answer:
P=20
Step-by-step explanation:
first find the distance between the points:
AB, BC,CD and DA
A(2,-3) , B(4,-3) , C(4,5) , D (2,5)
distance d= √(x2-x1)^2+(y2-y1)^2
for AB= d= √(4-2)^2+(-3-(-3))^2
AB=2
same thing for the rest of the lines
BC=√(4-4)^2+(5-(-3))^2
BC=8
CD=2
DA=8
perimeter=8+8+2+2=20
