The dog park is 9 m long if it covers 3 3/8 square miles how wide is it

Assuming that the park is of rectangular shape, we'll work with the area of rectangle formula:

Area = Length × Width

Given:  Length = 9 and Area = 3(3)/(8)

Find: Width = ?

∵ Area = Length × Width

∴ We substitute the Area with 3(3)/(8) and the Length with 9

∵  3(3)/(8) = 9 × Width

∴ Width = 3(3)/(8) ÷ 9

Converting 3(3)/(8) into an improper fraction:

3(3)/(8) = (27)/(8)

(27)/(8) ÷ (9)/(1) = (27)/(8) × (1)/(9) = (3)/(8)

∴ Width of the dog park = (3)/(8)

Verification: 3(3)/(8) = 9 × (3)/(8)
