Is the price of a piece of cloth a function of the length of the cloth? Explain

Answer 1

Yes, the price of a piece of cloth of a given width is determined by the price (P)) per yard (metre) and the length (L) of the cloth.

Since the price per unit length (P) is usually a constant, so we can express the price of cloth as
Price of cloth = f(L) = P*L
which is a function of the length L.
