a rectangle has the length of 3x+2 and a length of 2 x. Which expression shows the perimeter

Answer 1

The perimeter of a rectangle is equal to the length of all four sides added together. We use this formula to figure it out:

P = 2L + 2W

where P = perimeter, L = length, and W = width.

We know that L = 3x + 2 and W = 2x (the problem, as you wrote it, says "length" is 2x but you already said that length is 3x + 2 so I think you might mean width there).

So:

P = 2 (3x + 2) + 2 (2x)

P = 6x + 4 + 4x

P = 10x + 4
