Answer:
The length of the rectangular garden is 2·x - 5
Explanation:
The given area of the rectangular garden = 6·x - 15
The width of the rectangular garden = 3
Therefore, we have;
The area of a rectangle = Length × Width
The area of the rectangular garden = 6·x - 15 = Length of the rectangular garden × Width of the rectangular garden
6·x - 15 = The length of the rectangular garden × 3
Therefore;
The length of the rectangular garden = (6·x - 15)/3 = 2·x - 5
The length of the rectangular garden = 2·x - 5
