The formula A = bh/2 is used to find the area of a triangle whose base length(b) and height(h) are known. But, you might not have these two measurements at your disposal all the time, which is when Heron’ formula comes to help. For instance, visualize this scenario. Mr. Will surveys a triangular piece of land of dimensions 130 ft, 230 ft, 300 ft. What is the surveyed area? As you can see, you don’t have the height or base length here. Don’t freak out! Put Heron’s formula to work. Here’s how it works – the formula states the area of a scalene triangle A = √(s(s-a)(s-b)(s-c)) where a, b, and c are the side lengths of the triangle, and s is the semi-perimeter, a + b + c /2. Now, the area of the land surveyed by Mr. Will would be 14071.25 sq.ft approximately. Check this for yourself!
