Program to Calculate the Area of a Triangle"},"content":{"rendered":"\n<p>In this post, we will learn<strong> how to calculate the area of a triangle using Python<\/strong> Programming language.<\/p>\n\n\n\n<p>One of the easiest way to calculate the area of the triangle is by using the<strong> Heron\u2019s formula<\/strong>:<\/p>\n\n\n\n<p><strong>Area of Triangle = (s * (s &#8211; a) * (s &#8211; b) * (s &#8211; c)) ** 0.5<\/strong>, where <strong>a<\/strong>,<strong> b<\/strong> and <strong>c<\/strong> are the three sides of the triangle and <strong>s<\/strong> is the <strong>semi-perimeter<\/strong> of the triangle.<\/p>\n\n\n\n<p>We will be computing the area of the triangle using the following methods:<\/p>\n\n\n\n<ol><li>Using Standard Method<\/li><li>Using Functions<\/li><li>Using Math File<\/li><li>Area of Right Angled Triangle<\/li><\/ol>\n\n\n\n<p>So, without further ado, let\u2019s begin this tutorial.<\/p>\n\n\n\n<div id=\"ez-toc-container\"
