    width = 12 Inches

    length = 27 Inches

    Step-by-step explanation:

    Perimeter of Rectangle Formula is 2 (l+w), Therefore,

    2 (l+w) = 78 inches (Equation 1)

    l = 2x+3 (Equation 2)

    Let width be x

    Putting width as x and l as 2x+3 in equation 1

    2 (2x+3+x) = 78

    2 (3x+3) = 78

    6x+6=78

    6x=72

    x=12

    Putting width=>x = 12 inches in equation 2 to find the length

    l=2 (12) + 3

    l=27 inches
