Question

Hey frnds plzz Solve this question in proper way...No spam..The ans of this question is 9000cm..

Answer 1

heya!!

here is your answer! !☺☺

First of all there is a mistake in your question that its not the circumference it is the perimeter given.

Now,the solution =>

Let the sides of the triangle be 12x,17x and 25x.

Given, perimeter =540

Then,

12x+17x+25x=540

=>54x=540

x=540/54

=>10

Then,

12x=12×10=120

17x=17×10=70

25x=25×10=250

Now,the sides of the triangle are 120,170 and 250.

Area of triangle = √s (s-a)(s-b)(s-c)

S=a+b+c/2

=>540/2

=>270

Area= √(270×(270−120)×(270−170)×(270−250)

=>9000 cm

Hope it helps you!!☺☺

Answer 2

HEY THERE....
UR ANS IS HERE ....

GIVEN ---
RATIO OF SIDES = 12:17:25
Perimeter of trigle = 540
Area of triangle = ????

so the sides are 12x , 17x , 25x
perimeter of triangle = side+side+side
540 = 12x +17x+25x
540 = 54x
540 /54 = x
x= 10

so the sides are
AB = 12x
= 12×10
=120
AC = 17x
= 17 ×10
= 170
BC = 25x
= 25 ×10
= 250

AREA OF TRIANGLE = underoot s (s-a) (s-b) ( s -c)

s= a+b+c/2
=120+170+250/2
= 540/2
= 270

area = underoot 270 ( 270 -120) ( 270-170) ( 270 -250)
= underoot 270 (150)(100)(20)
=underoot 8,10, 00,000
= 9000

so the area of triangle is 9000 cm
