Final answer:
The length of the rectangular garden is 89 meters.
Step-by-step explanation:
To find the length of a rectangular garden, we can use the formula for the area of a rectangle:
Area = Length × Width.
By substituting the given values, we get: 5251 m² = Length × 59 m.
To solve for the length, we can divide both sides of the equation by 59: Length = 5251 m² ÷ 59 m = 89 m.
So, the length of the garden is 89 meters.
