The answer to the problem is 28.
Since, this is parallelogram
so, opposite sides are equal
We will find value of sides
Calculation of AB:
we are given point A=(-2,3)
point B=(4,0)
we can use distance formula

now, we can plug values


Since, this is parallelogram
so, opposite sides are equal
so,

Calculation of AD:
point A =(-2,3)
point D=(-5,2)
we can use distance formula

now, we can plug values


Since, this is parallelogram
so, opposite sides are equal
so,

Calculation of AE:
point A=(-2,3)
point E=(-3,1)
we can use distance formula

now, we can plug values


(a)
we know that
perimeter of a parallelogram is sum of all sides
so,
perimeter is

now, we can plug values

...........Answer
(b)
we can use area of parallelogram formula

we can plug values

............Answer
Your answer will be 5850 30% of 4500 is 1350.
4500 + 1350 = 5850.
