Answer:
195 yards
Explanation:
remember a rectangle has 4 sides.
100 yards wide is how wide 1 side is. so 2 sides are 200 yards wide.
to determine the width you subtract 200 yards from 590 which give you the answer 390. finally to determine just one side of the length you need to divide 390 in two to get 195 yards.
Hope this helped have a good day or night!!
