Answer:
Let us draw the diagram first to understand it better ✓
The diagram is in the attachment
We have taken a rectangular park and named as ABCD✓
And a uniform path inside it with area = 1000m²
And the remaining portion inside the park is named PQRS
We have the dimensions of the rectangular park
So the area of the park is as follows
Area of PQRS = 2800-1000=1800m²
Now, let TS and RM be X m
So ,SR = (70-2x)m and QR= (40-2x)m
•°• Area of the portion PQRS is as follows
Now divide the equation by the cofficient of X²
So,
We need to do middle term so
So if X= 50 then breadth of the path is 50 m or if X= 5 then breadth = 5 m
