1-Write down the algorithm, and draw a flowchart to compute the area and the perimeter of a rectangle ,whose length and width are known ,bearing in mind that the equation of the area is : Area=L*W and that of the perimeter is: perimeter =2*(L+W)

2-Write down the algorithm and draw flowchart to calculate the area of a circle whose radius "R" is known, bearing in mind that the equation of the area is: Area=3.14*R*R

3-write down the algorithm and draw flowchart to calculate the number of years bearing in mind that the number of months is known

4-Write down algorithm and draw flowchart to enter two numbers, then print "the largest is ...?" and, "the smallest number is...?"

(start)-->/Input R/-->| A=3.14*R*R |-->/Print A/-->(End)
The following flowchart is used to calculate the area of a circle whose radius "R". Repeat drawing the flowchart so that it displays the message "not allowed" and exits from the program (when the value of "R" is negative).

6-Make the necessary modifications to the flowchart of the previous exercise, so that you can enter the required multiplication table; instead of printing thee multiplication table of "3" constantly.

7-Write down the algorithm and draw a flowchart to print out even numbers from 1 to 10

8-Draw the flowchart to print out the sum of odd numbers from 1 to 10

9-Draw the flowchart to print out the sum of even numbers from 1 to 10

Put right or wrong:

1-flowcharts use symbols and lines with arrows to represent an algorithm ( )
2-You can use any Geometric shape to represent Algorithms when drawing flowcharts ( )
3-Flowchart can be drawn using software only and can't be drawn on paper ( )
4-The symbol ( oval ) is used to represent both the start and the end ( )
5-The rectangle symbol represents only one processing operation ( )
6-The flow of steps will always be from top to bottom or from left to right ( )
7-The symbol /diamond\is used when a question has more than one alternative ( )
8-Two paths (lines) should come out from the diamond symbol ( )
9-The line with an arrow (flow line) should be from left to right or from top to bottom. ( )
10-The (Algorithm) is the first stage of Problem Solving ( )
