    In this question the main information's are already provided. Based on them the answer to the question can be easily deduced.

    Let us assume the width of the poster = x

    Then the length of the rectangle = 3x

    The perimeter of the rectangle = 24 inches

    we already know

    Perimeter = 2 (Length + width)

    24 = 2 (3x + x)

    24 = 2 * 4x

    24 = 8x

    x = 24/8

    = 3

    So the width of the rectangle is 3 inches

    Length of the rectangle = 3x

    = 3 * 3

    = 9

    So the length of the rectangle is 9 inches.

    24=3x+3x+x+x add like terms

    24=8x divide by 8

    3:x

    plug I'm 3 for x

    3*3=9 so length is 9

    and width is 3
