Question

sides of a triangle are in the ratio of 12:17:25 and its perimeter is 540 cm. find its area
​

Answer 1

Answer:

Let the sides be 12x, 17x, 25x.

Then, perimeter = 12x+17x+25x=540 (given)

= 54x = 540

=x = 540/54

= x= 10.

Hence 12x = 12*10= 120

17x= 17*10 = 170

25x= 25*10 = 250.

Hence S= 120+170+250/2 = 270

270-120 = 150

270-170= 100

270-250 = 20

Area of triangle = 8100000

= 900
