The area of the garden is the amount of space on the garden.
- The area of the total garden is (x + 15)(x + 20)
- The width of the pathway is 1 meter
The dimensions of the garden is given as:
15 meters by 20 meters
Let the width of the pedestrian pathway be x.
So, the area of the total garden is:
In (a), we have:
The total area is given as: 336.
So, we have:
