Question
Write a program to print the area and perimeter of a triangle having sides of 3, 4 and 5 units by creating a class named 'Triangle' with a function to print the area and perimeter.
Solution
Sure, here is a Python program that creates a class named 'Triangle' and includes a method to calculate and print the area and perimeter of a triangle.
import math
class Triangle:
def __init__(self, a, b, c):
self.a = a
self.b = b
self.c = c
def area(self):
# calculate the semi-perimeter
s = (self.a + self.b + self.c) / 2
# calculate the area
area = math.sqrt(s*(s-self.a)*(s-self.b)*(s-self.c))
return area
def perimeter(self):
# calculate the perimeter
perimeter = self.a + self.b + self.c
return perimeter
# create a triangle object
t = Triangle(3, 4, 5)
# print the area and perimeter of the triangle
print("Area of the triangle: ", t.area())
print("Perimeter of the triangle: ", t.perimeter())
In this program, we first import the math module to use the sqrt function for calculating the area. We then define the Triangle class with the init method to initialize the sides of the triangle. The area and perimeter methods calculate and return the area and perimeter of the triangle, respectively. Finally, we create a Triangle object with sides of 3, 4, and 5 units, and print its area and perimeter.

Write a program to print the area of a rectangle by creating a class named 'Area' having two methods. First method named as 'setDim' takes length and breadth of rectangle as parameters and the second method named as 'getArea' returns the area of the rectangle. Length and breadth of rectangle are entered through keyboard.
Create an abstract class named shape that contains two integers and an empty method named printarea().Provide three classes named rectangle, triangle and circle such that each one of the classes extends the class Shape. Each of the inherited class from shape class should provide the implementation for the method printarea(). Get the input and calculate the area of rectangle, circle and triangle.In the Main class, create the objects for the three inherited classes and invoke the methods and display the area values of the different shapes.2(length of rectangle)3(breadth)5(triangle breadth)6(Triangle height)4(circle radius)
Select the correct answerWhat will be the output of the following Java program? class shape { int breadth; int height; int area; void area() { area = 1/2 * breadth * height; } void area(int x) { area = x; } } class triangle { public static void main(String args[]) { shape obj = new shape(); obj.breadth = 4; obj.height = 4; obj.area(4); System.out.println(obj.area); } }Options04816
