To find the perimeter of a rectangle, you must use the formula, P = 2l + 2w.
Given the values l = 2x - 1 and w = x + 2, we can express algebraically the perimeter.
P+=+2l+%2B+2w
P+=+2%282x-1%29+%2B+2%28x%2B2%29
P+=+%284x+-+2%29+%2B+%282x+%2B+4%29 (distributive property)
P+=+4x+-+2+%2B+2x+%2B+4
P+=+6x+%2B+2
So the answer is P = 6x + 2.
