8ha+=+400m%2A+width
8ha%2A%28%2810000m%5E2%29%2F%281ha%29%29+=+400m%2Awidth
80000m%5E2+=+400m+%2A+width
%2880000m%5E2%29%2F%28400m%29+=+width
200m+=+width notice how the units (meters in this case) is treated as just another variable. This is important. Because if the units you get at the end don't 'make sense', you probably made a mistake somewhere.
Here we see the width is expressed in meters -- which is a valid units for length
