The rectangle below has an area of 144x^4144x 4 144, x, start superscript, 4, end superscript square meters and a width of 12x12x12, x meters. what is the length of the rectangle?
By definition, the area of a rectangle is given by: A = (w) * (l) Where, w: width l: length Substituting values we have: 144x ^ 4 = (12x) * (l) Clearing the length we have: l = (144x ^ 4) / (12x) l = 12x ^ 3 Answer: the length of the rectangle is: l = 12x ^ 3
