Answer :
The ratio of the smaller field to original field is: 1/4
The lenght of the original field is:L=100 yards.
The width of the original field is : W=60 yards.
The length of the smaller fields is,
[tex]\begin{gathered} l=L\times\frac{1}{4} \\ l=100\times\frac{1}{4} \\ l=25 \end{gathered}[/tex]The width of the smaaler feild is,
[tex]\begin{gathered} w=W\times\frac{1}{4} \\ w=60\times\frac{1}{4} \\ w=15 \end{gathered}[/tex]Thus, the length of the smaller feild is 25 yards and the width of the smaller feild is 15 yards.
