The side of a triangles are 8cm,12cm,17cm.find its perimeter and its are by using herons formula
Novay_Z [31]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the 3 sides, that is

perimeter = 8 + 12 + 17 = 37 cm

To use Heron's formula for area (A)

A = \sqrt{s(s-a)(s-b)(s-c)}

where a, b and c are the lengths of sides and s the semi perimeter

s = 37 ÷ 2 = 18.5

let a = 8, b = 12 and c = 17, then

A = \sqrt{18.5(18.5-8)(18.5-12)(18.5-17)}

   = \sqrt{18.5(10.5)(6.5)(1.5)}

   = \sqrt{1893.9375} ≈ 43.52 cm² ( to 2 dec. places )
