Question

the sides of a triangle are in ratio 15:13:14 and its perimeteris 168cm . find its area of triangle​

Answer 1

Answer:

4

Step-by-step explanation:

15x+13x+14x=168

42x=168

x=168/42

x=4

Answer 2

Answer:

Let the sides of the triangle be 15x, 13x, and 14x.

according to the problem

15x+13x+14x=168

42x=168

x=4

therefore, sides of the triangle are 60cm, 52cm and 56cm.

By using heron's formula, area= √s(s-a)(s-b)(s-c)

√84×24×32×28=√1806336=1344cm^2.
