Project Overview

The GeometryCalculator contract provides functions to calculate the area of three basic shapes:

• Triangle: Calculates the area given the base and height.
• Rectangle: Calculates the area given the length and width.
• Square: Calculates the area given the length of one side.

This project uses the Solidity programming language and is developed using the Hardhat framework. The contract has been deployed to the Lisk Sepolia testnet using Alchemy.

Features

• Triangle Area Calculation: Given a base and a height, the contract calculates the area of a triangle.
• Rectangle Area Calculation: Given the length and width, the contract calculates the area of a rectangle.
• Square Area Calculation: Given the length of one side, the contract calculates the area of a square.
• Error Handling: Ensures that the input values are greater than zero.

Prerequisites

To work with this project, you need to have the following installed:

• Node.js
• npm
• Hardhat
• Alchemy
• MetaMask (for deploying to testnets)

Setup and Installation

1. Clone the repository:

   git clone https://github.com/DonGuillotine/geometry-calculator.git
   cd geometry-calculator

2. Install dependencies:

   npm install

3. Set up environment variables:

   • Create a .env file in the root directory.

Deployment

To deploy the contract to the Lisk Sepolia testnet:

1. Compile the contract:

   npx hardhat compile

2. Deploy the contract:

   npx hardhat run scripts/deploy.js --network lisk-sepolia

3. After deployment, the contract address will be displayed in the console.

Testing

To run tests for the contract:

1. Run the tests:

   npx hardhat test

2. Review the output to ensure all tests pass.

Usage

You can interact with the deployed contract using the Hardhat console, Remix IDE, or by building a front-end dApp.
