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)
