A rectangle has a width, w, equal to 6 less than the length, l. Which expressions represent ways to find the perimeter of the rectangle? Select ALL that apply.

4 L plus 12
4L−12
2(L−6)+2l
2(6−L)+2l
12+2L+2L

4L-12

Step-by-step explanation:

let's assume the length = L

then the width of the rectangle is L - 6

perimeter = 2× (a+b)

where "a" and "b" are the length and the width of the rectangle.

so perimeter = 2× (L + L - 6)

2 × ( 2L - 6)

4L - 12
