Question

solve this if u can
Sides of a triangle are in the ratio 12:17:25 and its perimeter is 540 cm. Find its area.

Answer 1

Let the slides be 12x,17x,and 25x.


ATQ,
12x+17x+25x=540
29x+25x=540
x=540/54
x= 10.


Therefore sides=12x=12×10=120
,17x=17×10=170
,and 25x=25×10=250 .

Answer 2

ratio of the sides of a triangle are = 12:17:25
perimeter is =540
12x+17x+25x=540
54x=540
x=10
sides are 120,170,250
i t's semi perimeter is = 270
using heron's formula area of the triangle =

root {(s)(s-a)(s-b)(s-c)}
where s is the semiperimeter and a,b,c

area the sides of the triangle.

root {( 270)(270-120)(270-170)(270-250)}

= 9000cm^2.
