write a menu driven program to find the area of a circle ,perimeter of rectangle and area of quadrilateral
Answers
A rectangle is a flat figure in a plane.It has four sides and four equal angles of 90 degree each.In rectangle all four sides are not of equal length like square, sides opposite to each other have equal length.Both diagonals of rectangle have equal length.
example
Input : 4 5
Output : Area = 20
Perimeter = 18
Input : 2 3
Output : Area = 6
Perimeter = 10
Hope it helps ^_^
This program is in Java

double choice = sc.nextDouble();
