Answer:
71 yards.
Step-by-step explanation:
Since the field is rectangular in shape, the formula for finding the Area is L * W
where L = length, and W = width
From the question Area of the sport field = 6,450.35 square yards
this implies that L*W = 6,450.35 square yards
Also, given that the length of the field L = 90.85 yards
Therefore from the equation 90.85W = 6,450.35 square yards
W = 6,450.35 square yards ÷ 90.85 yards
W = 71 yards
Hence, the Width of the sport field is 71 yards.
