Perimeters and areas of Triangle
the mathematical equation to calculate the perimeter and area of a Triangle with height(h), length(l) and width(w) is :
p= h+l+w
a=1/2(l*w)
so with python it can be executed as
length=float(input("Enter length : "))
width =float(input("Enter width : "))
height=float(input("Enter height: "))
print("the perimetre of the triangle is : " +str(length+width+height))
print("the area of the triangle is : " +str(1/2*(length*width)))
and the output will be
Enter length : 2
Enter width : 3
Enter height: 4
the perimeter of the triangle is : 9.0
the area of the triangle is : 3.0
Perimeters and areas of rectangle
the mathematical equation to calculate the perimeter and area of a Rectangle with length(l) and width(w) is :
p= 2l + 2w
a= l*w
and the code will be
length=float(input("Enter length : "))
width =float(input("Enter width : "))
print("the perimeter of the rectangle is : "+str(2*length+2*width))
print("the area of the rectangle is : "+str(length*width))
and the output will be
Enter length : 2
Enter width : 3
the perimeter of the rectangle is : 10.0
the area of the rectangle is: 6.0
Perimeters and areas of Circle
the mathematical equation to calculate the perimeter and area of a Circle with radius(r) is :
p= 2*PI*r
a=PI*r**2
so with python it can be executed as
from math import pi
r=float(input("Enter radius : "))
print("the Perimetre of the circle with radius "+str(r)+" is : " +str(2*pi*r))
print("the area of the circle with radius "+str(r)+" is : " +str(pi*r**2))
and the output will be
Enter radius : 3
the Perimeter of the circle with radius 3.0 is : 18.84955592153876
the area of the circle with radius 3.0 is : 28.274333882308138
