WebJan 10, 2010 · Yes. Heron's Formula works on all triangles. A=1/2bh The area of a triangle is 1/2bh. If the base of it is a triangle and all 4 of the triangles aren't the same, then you have to find the area of the base triangle and then the three other triangles (which should all have the same area). WebMar 8, 2015 · Bit late on this I know. Heron's formula is fun but often painful and long; most of the time in GCSE it would be much more work. It is also off-syllabus as the GCSE course tries to teach you trigonometry - so there is no point in teaching you shortcuts for trigonometry right now as the cosine rule etc. will lead on to more important and difficult … WebFeb 20, 2024 · Follow the following steps to find the area of a triangle using Heron’s formula. Step 1: Calculate the perimeter of the given triangle. Step 2: Divide the value of the perimeter by 2 to get the semi-perimeter of the given triangle; S = (a+b+c)/2. Step 3: Use Heron’s formula A = √ (s (s – a) (s – b) (s – c) to find the area of the ... csr secondary stakeholder
