Siobhan wants to find a rectangular plot of land with an area of 57 ms. if she
finds a plot whose width is 15 m, what must be the length? is this an example
of direct variation or inverse variation?

Area is length times width.

You are given the area and the width, so to find the length, divide the area by the width:

Length = Area /  width

Length = 57 / 15 = 3.8 m.

Because the width is given as a set number, 15m, this would be a direct variation.
