find the perimeter
length: x^2 - 9
width: x^2 - 4
To find the perimeter of a rectangle, we use the formula:
Perimeter = 2(length + width)
Given:
Length = x^2 - 9
Width = x^2 - 4
Substitute these values into the formula:
Perimeter = 2(x^2 - 9 + x^2 - 4)
Perimeter = 2(2x^2 - 13)
Perimeter = 4x^2 - 26
So, the perimeter of the rectangle is 4x^2 - 26.
