составим сначала длину участка, составим пропорцию:

240,8-28%

х-100% где х-это длина участка

х=240,8*100/28

х=860(м)

площадь прямоугольного участка находим по этой формуле : S=a*b, где а -длина участка, b

-ширина

S=860*240,8=207088( КВ.м)

раз ответ нужно получить в гектарах, переведём полученный результат в гектары по формуле 1га=10000м

получается S=207088/10000=20,7088,округляем до десятых, получаем S= 20,7(КВ га)

площадь участка 20,7 КВ га

можно лучший ответ пж
