Question
One of the longest sides of the triangle is 20 m. The other side is 10 m. Area of the triangle is 80 m2m2. What is the another side of the triangle?
Answers
If a,b,c are the three sides of the triangle.
Then formula for Area = (s(s–a)×(s–b)×(s–c))−−−−−−−−−−−−−−−−−−−√(s(s–a)×(s–b)×(s–c))
Where s = (a+b+c)2=12×(30+c)(a+b+c)2=12×(30+c)
[Assume a = 20 ,b = 10]
