при таком масштабе в каждом см карты содержится 50000см местности или 500 м. значит ширина участка 2*500=1000 м  а длина участка 3*500м = 1500м значит площадь равна 1000*1500=1500000 м² = 1.5 кв. км


tomashevich05: Спасибо большое, но как это в письменном виде записывать? (извините за лишний вопрос)
Аноним: 1:50000=2:100000=3:150000 100000см*150000см =
