The solution would be like this for this specific problem:
Area = L * W = 600
Length = W + 25
Substitute and solve for "W":
(W + 25)W = 600
w^2 + 25w - 500 = 0
(w - 15) (w + 40) = 0
Positive solution:
Width = 15 meters
Length = 15 + 25 = 40 meters
So, the dimensions of the playground using an
algebraic solution is 15 meters by 40 meters.
To add, the minimum number of coordinates needed to
specify any point within it is the informal definition of the dimension
of a mathematical space.
