If the sides of a rectangle are 2x and 3x, then the perimeter is 2(2x + 3x) = 10x. The area is 2x * 3x = 6x².
P = 10x
A = 6x²
D) None of the above.

If you are saying: 2x, 2x, 3x, 3x for the sides then,
D. none of these
Because, length times width is 2x times 3x which is 6x^2 and 2x + 2x + 3x + 3x = 10x.
If you are saying what you typed, 2x, 2 3x, 3x then I have no idea what that means.
