A square Water Fountain is Surrounded by a walk 2 yards wide.
If the Area of the Fountain is 2/3 of the total area of the Fountain and the Walk.
What are the Outside Dimensions of the Walk
Draw a diagram!
Suppose the fountain is $x$ yards by $x$ yards. What is its area?
What are the dimensions of the fountain plus the walk? What is the area of the fountain plus the walk?
The area of the fountain is $\frac23$ this area.
Solve for $x.$
