Чему равны стороны прямоугольника, если его периметр равен 50 см, а площадь — 66 см2?

Answers & Comments

zemellana Х см - одна сторона прямоугольника ;
у см - другая сторона;
2(х+у) см - периметр прямоугольника;
х*у кв. см - площадь прямоугольника; Составим два равенства и решим систему двух уравнений с двумя неизвестными:
{2(х+у) =30;
{x*y=50. Решив систему, найдем х =10; у=5.
