Write a C++ code for task 2 according to given condition.

 

Task # 02. Create a class Rectangle keeping in mind that rectangle have length and width. One should be able to calculate the perimeter () and the area () of the rectangle, can set a value to length and width and retrieve the value of Length & width. Where 0 < length < 21 0 < width < 21 Area of Rectangle-length*width; Perimeter of Rectangle = (length + width) *2; TEST PLANS Commands Output Rectangle r; r.set (2); r.getLength (); r.set (50); r.getLength (); Rectangle f=r3B f.set (-20); f.getLength ();
