A rectangle's width is 2 meters shorter than its length, l. Its area is 168 square meters. Which equation can be used to find the length of the rectangle?

l (l - 2) = 168

l (l + 2) = 168

2l 2 = 168

l 2 = 168

    l (l - 2) = 168

    Step-by-step explanation:

    Let w = width

    Let l = length

    Let A = area

    w = l - 2

    A = l * w

    also, A = 168

    equating the two values of A

    l * w = 168

    l * (l - 2) = 168

    l^2 - 2l = 168

    l (l - 2) = 168
