Question

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?

Answer 1

Answer: 3.8m; inverse variation

Step-by-step explanation: just did it on A P E X

Answer 2

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.
