Explanation:
Since perimeter is adding the 4 sides all together, we must add the width twice by it's self, or multiply by 2.
65 x 2 = 130.
Then, we must subtract the perimeter by the total width to get the total length.
304 - 130 = 174.
Therefore, our length is 174 because we had to add or multiply the width 2 times, because there are 2 sides of width, and 2 sides of length.
Then, we had to subtract the perimeter by the total width to find the answer of the total length.
Although our answer isn't just 174, it's 174 yards. You always need to label your work and answer.
Best of Luck!
