the area of a square is represented by 9x^2-12x+4 which expression represents the perimeter of the square?

A3z-2
B3z+2
C6z-4
D12z-8

Verified Answer :

well to tell ya the truth this is very easy to find the perimeter you have to add right?so the answer must be 3z+2 

The perimeter of the square will be represented by 12x-8.

What is a square?

A quadrilateral in which all sides are equal and all angles are the right angle.

Area of a square = side²

side = \(\sqrt{area}\)

side = \(\sqrt{9x^2-12x+4}\)

side = \(\sqrt{9x^2-6x-6x+4\\\)

side = \(\sqrt{3x(3x-2)-2(3x-2)}\)

side = \(\sqrt{(3x-2) (3x-2)}\)

side = \(3x-2\)

as we know that

perimeter of square = 4(side)

perimeter of square = 4(3x-2)

perimeter of square = 12x-8

Hence, the perimeter of the square will be represented by 12x-8.
