To find the area of a rectangular garden, you need to multiply its length by its width. In this case, the width is 9 meters.
1. Let's first determine the length of the garden, which is given as double the width. Since the width is 9 meters, the length will be 2 times the width, which is 9 x 2 = 18 meters.
2. Now that we have the width (9 meters) and length (18 meters), we can calculate the area of the garden by multiplying these two values together: 9 meters x 18 meters = 162 square meters.
Therefore, the area of the rectangular garden that is 9 meters wide and has a length double the width is 162 square meters.
