Question

If a b c are the lengths of the three side of a triangle then area of triangle

√s(s-a)(s-b)(s-c), where s= perimeter of triangle. ( True or false )​

Answer 1

Answer:

You can calculate the area of a triangle if you know the lengths of all three sides, using a formula that has been known for nearly 2000 years.

It is called "Heron's Formula" after Hero of Alexandria (see below)

Just use this two step process:

Step 1: Calculate "s" (half of the triangles perimeter):

s = a+b+c2

Step 2: Then calculate the Area:

herons formula A = sqrt( s(s-a)(s-b)(s-c) )

Step-by-step explanation:

Answer 2

It is called hero's formulae. A,b,c are the three sides of the triangle. S will then = a+b+c/2.
