Question

the side of a triangle are in the ratio 13 : 14 : 15 and its perimeter is 84 cm find the area of the triangle

Answer 1

Let the sides be 13x,14x,15x
given perimeter=84cm
therefore 13x+14x+15x=84
x=2
therefore sides are 26,28,30
area =sqrt(s*(s-a)*(s-b)*(s-c))
=336cm^2

Answer 2

Answer:

2730

Step-by-step explanation:

let area of triangle be x.

As per the condition- x=13 into 14 into 15

x=2370
