Answer:
We have points
A(-3,4),B(3,4),C(-3,-2),D(3,2)
Now distance between Aand B
AB= root (x2 - x1) ^2 + (y2-y1) ^2
=Root (3+3)^2+(4-4)^2
=root 9^2
=9 units
And, same as B and C
BC=root (x3-x2) ^2+(y3-y1)^2
=root(81+36)
= root117
=3root13 units
As same CD
=root (81+16)
=root 97
And same DA
= root 85
Adding these
AB+BC+CD+CA
= 9+3root13+root97+root85
Use calculator and add them, then u will get your answe
