Question

Calculate the area of Triangle ABC. Can i Get the answer plz? only need the correct answers.. not like "i don't know" etc..​

Answer 1

Ofcourse you can get answer

And i know answer

$\large \sf \: here \: \: is \: \: the \: \: answer : )$

Given

• a = 43cm
• b = 32cm
• c = 64cm

In triangle ABC

• By Herons Formula

$\\ \large \tt \mapsto \: s = \frac{a + b + c}{2}$

• a , b , c = sides

$\\ \large \tt \implies \: s = \frac{43 + 32 + 64}{2} \\ \\ \\ \large \tt \implies \: s = \frac{139}{2} \\ \\ \\ \large \sf \leadsto\: s = 69.5cm$

Herons Formula

$\\ \large \tt \: ar. = \sqrt{s(s - a)(s - b)(s - c)}$

$\large \tt \: = \sqrt{69.5(69.5 - 43)(69.5 - 32)(69.5 - 64)} \\ \\ \large \tt \: = \sqrt{69.5(26.5)(37.5)(5.5)} \\ \\ \large \tt \: = \sqrt{379860.9375} \\ \\ \large \tt \: area = 616.329 (approx)$
