Question

the side of a triangle are in the ratio 5 : 12 :13 and the perimeter is 150 cm the area of triangle is ​

Answer 1

Answer:

Step-by-step explanation:

Given

2s=150

Let the sides be 5x+12x+13x=150

Then,

30x=150

X=5

Now for semiperimeter

2s=150

S=75

Now

Area of triangle=

',√s(s-a)(s-b)(s-c)

Now

√75*50*15*10

√15*5*5*10*15*10

√15*15*5*5*10*10

15*5*10

750cm²

Hope u got it now

Answer 2

Answer:

Step-by-step explanation:  

let us take the unknown value as x

5x+12x+13x= 150 cm

30x=150cm

x=150/30

x=5

5x=25cm

12x=60 cm

13x=65cm

Use herons formula

√s(s-a)(s-b)(s-c)

s=25+60+65= 150/2= 75

√75*50*15*10

=$750cm^{2}$
