C++ program.

Write the definition for a class called Rectangle that has floating point data member length and width. The class has the following member functions:

void setlength(float) to set the length data member

void setwidth(float) to set the width data member

float perimeter() to calculate and return the perimeter of the rectangle

float area() to calculate and return the area of the rectangle

void show() to display the length and width of the rectangle

int sameArea(Rectangle) that has one parameter of type Rectangle. sameArea returns 1 if the two Rectangles have the same area, and returns 0 if they don't.

1. Write the definitions for each of the above member functions.

2. Write main function to create two rectangle objects. Set the length and width of

the first rectangle to 5 and 2.5. Set the length and width of the second rectangle

to 5 and 18.9. Display each rectangle and its area and perimeter.

3. Check whether the two Rectangles have the same area and print a message

indicating the result. Set the length and width of the first rectangle to 15 and

6.3. Display each Rectangle and its area and perimeter again. Again, check

whether the two Rectangles have the same area and print a message indicating

the result.
