Question
If sides of a triangle are 3,5,7 then the area of that triangle is -
Answer: Option A
:
A
We know the area of a triangle can be calculated using its sides through Heron's formula
√s(s−a)(s−b)(s−c)
Where "s" is the semiperimeter of the triangle.
And a, b, c are the sides of it.
So, s=3+5+72=7.5
And Area = √7.5(7.5−3)(7.5−5)(7.5−7)
=√42.18
