Question

Write the Minimum requirements to find the area of of triangle using heron's formula

Answer 1

Answer:

you must know the semi-perimeter.

Step-by-step explanation:

Answer 2

Step-by-step explanation:

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) )

Example: What is the area of a triangle where every side is 5 long?

Step 1: s = 5+5+52 = 7.5

Step 2: A = √(7.5 × 2.5 × 2.5 × 2.5) = √(117.1875) = 10.825...

Try it yourself:

Heron's FormulaFind a Triangle's Area from its SidesClassic Heron's Formula:

s = (a+b+c)/2 = 6

Area = √( s(s-a)(s-b)(s-c) )

Area = 6Variation with less rounding error:

Sides in Descending Order: 5,4,3

Area = √((a+(b+c))(c-(a-b))(c+(a-b))(a+(b-c)))/4

Area = 6
