Ответ:

В. 420

Пошаговое объяснение:

По условию бассейн квадратный и площадь равна 3600, следовательно, сторона квадрата равна 60м.

Весь парк тоже квадратный и площадь его равна 44100, то есть, сторона равна √44100 = 210 м.

Определим стороны прямоугольника А:

Меньшая сторона равна 60

Большая сторона равна 210-60=150

Периметр аттракциона Р равен

P=2*(60+150)= 420 м.
