Determine the missing side of a rectangle with an area
of 144 cm² and a width of 8 cm. Please show your work.


  1. Answer:
    Length is equal to 18
    Step-by-step explanation:
    The formula for finding the area(A) of a rectangle in Length(L) times width(W): A=(W)(L). If we plug in the given information into the equation, you will get 144=(8)(L). From there we solve for L.
    144 = (8)(L)
    144/8 = (8)/8 (L)
    18 = L
