Draw a flowchart and write a program in QBASIC to calculate the area and the perimeter of 10 different rectangles. Take the length and breadth as inputs and display the result.
Answer
Flowchart
QBASIC Program
Cls
For I = 1 To 10
Input "Enter length and breadth"; L, B
A = L * B
P = 2 * (L + B)
Print "Area = "; A
Print "Perimeter = "; P
Next I
End
Output
Enter length and breadth? 2,1
Area = 2
Perimeter = 6
Enter length and breadth? 2,3
Area = 6
Perimeter = 10
Enter length and breadth? 2,4
Area = 8
Perimeter = 12
Enter length and breadth? 3,4
Area = 12
Perimeter = 14
Enter length and breadth? 3,5
Area = 15
Perimeter = 16
Enter length and breadth? 3,6
Area = 18
Perimeter = 18
Enter length and breadth? 4,5
Area = 20
Perimeter = 18
Enter length and breadth? 5,8
Area = 40
Perimeter = 26
Enter length and breadth? 6,9
Area = 54
Perimeter = 30
Enter length and breadth? 7,8
Area = 56
Perimeter = 30
