    The legth of the rectangle is 4.5 units

    Step-by-step explanation:

    To solve this we first have to know the formula to calculate the area of a rectangle

    a = area 27 square units

    l = length

    w = width = 6 units

    a = l * w

    because we want to calculate the length, we will have to clear the l

    a = l * w

    l = a / w

    now we replace with the known values

    l = 27 u² / 6u

    l = 4.5 u
