On a coordinate plane, shapes show the size of swings, a slide, a merry-go-round, and a sandbox. The sandbox has points (0, 6), (8, 12), (12, 6), and (8, 0).
A sandbox is shaped like a kite. A planner would like to replace the wooden border around the sandbox. How many feet of wood does he need? Round up to the nearest whole number.

Compute side lengths with the distance formula.

Between (0,6) and (8,12): sqrt[(8-0)^2 + (12-6)^2] = sqrt(64+36) = 10
Between (8,12) and (12,6): sqrt[(12-8)^2 + (6-12)^2] = sqrt(16+36) = sqrt52
Between (12,6) and (8,0): same as previous = sqrt52
Between (8,0) and (0,6): same as first = 10

Perimeter = 10 + sqrt52 + sqrt52 + 10 = 20 + 2·sqrt52 = 20 + 4·sqrt13 ≈ 34.422

Rounding up gives 35 feet.
