Question

sides of a triangle has perimeter
of 12, 17:25 and perimeter is
suo cm, Find it's area​

Answer 1

Step-by-step explanation:

Given side in ratio - 12:17:25

Therefore, Sides of a Triangle = 12x , 17x ,25x

Perimeter=540 cm

perimeter of a Triangle : sum of all sides

540= 12x + 17x +25 x

540= 54 x

x = 540÷54

X= 10

12× 10 =120 cm

17 × 10 = 170 cm

25×10 = 250 cm

semi-perimeter (s) : a+b+c÷2

120+170+250÷ 2

540÷2= 270 cm

using Heron's Formula √s(s-a)(s-b) (s-c)

√270(270-120)(270-170)(270-250)

√270(150)(100)(20)

√81000000

9000 cm²
