Algorithm:-

Step 1:- start.

Step 2:- declare variables length,breadth, radius, aor, por, aoc, coc;

Step 3:- take input of Length and Breadth of the Rectangle.

Step 4:- take input of Radius of the Circle.

Step 5:- calculate the area and perimeter of the rectangle, and the area & circumference of the circle. As follow:-

/*

aor: area of rectangle

por: perimeter of rectangle

aoc: area of circle

coc: circumference of circle

*/

aor = length*breadth;

por= 2*(length+breadth);

 

 

aoc = 3.14*radius*radius;

 

coc = 2*radius*3.14;

Step 6:- print the values.

Step 7:- END.
