Question

the sides of the triangle are in the ratio 15 :13 : 14 and its perimeter is 168cm find the area of the triangle​

Answer 1

Step-by-step explanation:

let suppose sides are... 15x,13x,14x,

then according to question

15x+13x+14x=168

42x=168

x=168/42

x=4

then sides are 60,52,56

now area of triangle by herons formula

=√84(84-60)(84-52)(84-56)

=√84(24)(32)(28)

now solve it u will get

ur answer
