Area of a Triangle

Area of a Triangle

Program Description:

This program is designed to find the area of a triangle. The user will input a positive number for the base and the height. The program will then use the area of a triangle formula (area = ½ x b x h). The program will then use the numbers that the user entered and the area will be calculated.

Analysis:

I will define two integers which are base and height. I will then float area which the program will use the area of a triangle formula to calculate. The area of a triangle formula will use the numbers the user entered for the base and the height and multiply them along with (½). The area of a triangle is as follows:

area = 0.5* base * height

For example

Base = 6

Height = 12

area = 0.5 * 6 * 12

area = 0.5 * 6 = 3

area = 3 * 12 = 36

area = 36

Test Plan:

Test Case | Input | Expected Outcome |

1 | Base = 6Height = 12 | Area of the triangle is 36 |

Pseudocode

//This program will calculate the area of a triangle using the area of a triangle formula

//Start main program

Main

//Declare Variables

Base, Height

//Float the area

Area

//String statement for base and height

print “Enter the base of the triangle”

print “Enter the height of the triangle”

//Area of triangle formula

area = 0.5 x base x height

//End main program

End Program
