Area is length times width. So, we have the value for area (1917) and width (9). Let's plug that into the equation (A=LW) 1917=9L divide by 9 to find L 1917/9=213 So, if the width is 9 feet and the area needs to be 1917 square feet, then the length is 213 feet.
Area equals width multiplied by length. Set up the equation as 9x=1917. The x represents the unknown length. The 9 represents the given width. Divide 1917 by 9 resulting in x=213. The length of the garden is 213 feet.
