    length = 9 cm

    Step-by-step explanation:

    perimeter = p = 26 cm

    width = w = 4 cm

    perimeter of a rectangle = 2*w+2*L

    L = length

    so we have:

    26 = 2 * (4) + 2*L

    26 = 8 + 2L

    26-8 = 2L

    18 = 2L

    L = 18/2

    L = 9 cm = length

    Length would be 9 centimeters.

    Step-by-step explanation:

    A rectangle has a width of 4 centimeters and a perimeter of 26 centimeters.

    Perimeter = 2 (Length + Width)

    Let the length of the rectangle be 'L'

    2 (L + 4) = 26

    2L + 8 = 26

    2L = 26 - 8

    2L = 18

    L = 18/2

    L = 9

    Length would be 9 centimeters.
