Question

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?

Answer 1

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
