矩形的面积和周长程序-yiteyi-C++库

矩形是平面上的平面图形。它有四条边和四个相等的90度角。在矩形中，所有四条边的长度不像正方形一样相等，相对的边的长度相等。矩形的两条对角线长度相等。

例如：

Input : 4 5Output : Area = 20         Perimeter = 18Input : 2 3Output : Area = 6         Perimeter = 10

推荐：请尝试你的方法 {IDE} 首先，在进入解决方案之前。

公式：

Area of rectangle : a*b Perimeter of rectangle: 2*(a + b)
