The area of the square is 2304 square units.
Given the side of the square measures [tex]3mn^{2}[/tex]
We have to find the area of the square when m = 4 and n = -2
Putting the value of m and n in the expression to get the value of side of the square -
Side = [tex]3mn^{2}[/tex] = [tex]3*4*(-2)^{2}[/tex] = [tex]48[/tex]
Thus the length side of the square is 48 units.
As the square has all of its 4 sides equal, thus the area of the square is = side*side .
∴ Area of the given square = side*side = 48*48 = 2304 square units.
