Let W be the width of the pool plus walk

Let L be the length of the pool plus walk

Total Area of Pool + walk = W * L = 212 Square Meters

L = W + 5 meters

So Area = W * ( W + 5) = 212

or W^2 +5W -212 = 0

Using the Quadratic equation

W = 12.27 Meters

L = 17.27 Meters

Need to subtract 4 meters from each to account for the walk around the pool.

The pools size is 8.27 Meters Wide and 13.27 meters long.
