Answer:
Width = 21m
Explanation:
The diagrammatical representataion of the rectangular park is as shown;
Given the following
Length = 28meters
Diagonal = 35metres
Required
Width
Using the pythagoras theorem;
[tex]\begin{gathered} 35^2=w^2+28^2 \\ w^2=35^2-28^2 \\ w^2\text{ = }1225-784 \\ w^2=441 \\ w\text{ =}\sqrt[]{441} \\ w\text{ = 21m} \end{gathered}[/tex]Hence the width of the park is 21metres
