The uniform width path is AROUND the swimming pool.

Entire area of the path and the pool: %2830%2B2x%29%2820%2B2x%29.

The area of only the surrounding path: %2830%2B2x%29%2820%2B2x%29-30%2A20.
Simplify this.
30%2A20%2B100x%2B4x%5E2-30%2A20
highlight_green%284x%5E2%2B100x%29



(b)
4x%5E2%2B100x=360
Solve this.
