Question

the sides of a triangle are in the ratio 5 :12 :13 and its perimeter is 150 metre. find the area of the triangle.​

Answer 1

Step-by-step explanation:

Perimeter(P)=150m

P=sum of all sides

let the unknown=x

5x+12x+13x=150

30x=150

x=150/30

x=5

lengths of sides of the triangle are:

5x=5*x=5*5=25m

12x=12*x=12*5=60m

13x=13*x=13*5=65m

semiperimeter=P/2=150/2=75m

so using herons formula we can find the are of the triangle
