Step-by-step explanation:
A rectangle has a length that is 8 times the width
The area of the park is 392 square units
Let y represent the width of the park
Since the length is 8 times the width then, l= 8x
Therefore the width of the park can be calculated as follows
8x × x= 392
8x^2= 392
x^2= 392/8
x^2= 49
x= 7
Hence the width of the park is 7
