Raheem is writing a computer program that will take in the base and height of a triangle as inputs from the user and outputs the area using the formula: area $=0.5$ (base $x$ height). Using AQA Pseudo-code, complete the program: Raheem decides to rewrite the calculation as a subroutine called areaTriangle (), that takes the base and height as parameters and returns the area. Rewrite the program above as a subroutine, using either AQA Pseudo-code or a high-level programming language you have studied.

Key Concepts

Subroutines

Subroutines, also known as functions or procedures, are self-contained blocks of code designed to perform a specific task. They allow a program to be broken down into smaller, manageable parts which can be reused throughout the program, making the code more organized and easier to maintain.

Parameters and Return Values

Parameters are values passed into a subroutine, and return values are the results that the subroutine outputs after processing. This concept enables functions to be dynamic and reusable by working with varying inputs while providing a result that can be used elsewhere in the program.

Modularity

Modularity is a programming principle that involves dividing a program into distinct sections or modules, such as subroutines, each handling a specific part of the program's functionality. This approach enhances readability, facilitates debugging, and simplifies code reuse and maintenance.

AQA Pseudo-code

AQA Pseudo-code is a structured, language-independent form of code used to teach algorithm design and problem-solving concepts. It provides clear syntax and logical structure while abstracting away the complexities of full programming languages, making it ideal for educational purposes.

Transcript

00:01 Hello welcome to this lesson and this lesson will write a python program to calculate the area of a triangle giving the three sides a b and c all right so first of all let's have the side a so we convert it to floats and we say enter the length of side a right on the first side in the same way we have b we convert the equal to float then we say enter the length of side b alright then again we convert the side c also to a float so we say enter the length of side c let me fix something up here.

01:15 Then let's have x which is equal to the a plus b plus c divided by 2.

01:24 Okay.

01:25 Then now we can have the area which is equal to the whole of this to the the power 0 .5 which represent the square root of that okay then we can print the area of a triangle is this but before then i'll say the area of a triangle with sides then we'll have the a b and c so we'll have the area of the triangle go with sides a b and c okay is then we we have put the area okay so let's run to see the running game play my console suicide a less have five for it so i'd be less laughs around inside let's have eight all right this is a view of the time go aside five seven and eight is this right so let me bring a comma there so that it makes it redouble so between this i'm going to bring a comma all right all right so i have a b and c okay let's run again so have 15 15, 12, and 30.

04:25 It says the area with this is equal to c.

04:30 Okay.

04:31 So we can round the answer to any decimal place.

04:35 So for example, if we decide to round using round, rounding this to two decimal places...
