Step-by-step explanation:
Let the area of rectangle with given points are as follows :
A(-3,3)
B(3,2)
C(4,-1) = C( x1,y1)
D(-2,-3) = D( x2, y2)
Now,
- The distance of CD = root under
(x2-x)^2 +( y2 - y1)^2
= root under (-2-4)^2 + ( -3+1)^2
= root under (-6)^2 + (-2)^2
= root under 36 + 4
= root under 40
= 2root 10
Therefore; the unit number if CD is 2 root 10.
