Answer:
60 yards.
Explanation:
We can use the concept of proportional relationships to find the width of the field for 11-14 year-old players.
The ratio of length to width of the field for 9 and 10 year-old players is:
75 yards : 45 yards
We can simplify this ratio by dividing both sides by 15:
5 yards : 3 yards
This means that for every 5 yards in length, the field is 3 yards wide.
Now we can use this ratio to find the width of the field for 11-14 year-old players:
Ratio of length to width for 11-14 year-old players:
100 yards : w yards
where w is the unknown width.
We can set up a proportion using the ratio we found for the 9 and 10 year-old players:
5 yards : 3 yards = 100 yards : w yards
To solve for w, we can cross-multiply:
5 yards x w yards = 3 yards x 100 yards
5w = 300
w = 60
Therefore, the width of the field for 11-14 year-old players is 60 yards.
