Width; 5x
Length:  8x
Area:  9,000 sq meters

Equation:
Length × Width = Area

(8x) (5x) =9,000 meter²

40x = 9,000  meter²

40x²/40 = 9000 meter²/40

x² = 225 meter²

 \sqrt{ x^{2} } =  \sqrt{225 meter ^{2} }

x = 15 meters

Dimensions of rectangular field:
Width: 5x = 5 (15) = 75 meters
Length: 8x = 8 (15) = 120 meters

ANSWER:  The length of rectangular field is 120 meters.

Check:
Length x Width = 9000 meter²

(120 meter) (75 meter) = 9000 meter²

9000 meter² = 9000 meter²

Ratio of width to length ⇒  75 : 120   or 5 : 8 (lowest term)
