Question

The perimeter of the triangle is 44 cm if the sides are in the ratio 9:7:6 find its area

Answer 1

Let the sides of the triangle be,

9x, 7x, 6x

s = a +b +c/2

s = 9x + 7x + 6x/2

s = 11x

a = s(s – a)(s – b)(s – c)

Answer 2

Answer:

let the ratio be x cm

So, Sides of the triangle are 9x, 7x and 6x

But, the perimeter of the triangle is 44cm

According to the question

9x + 7x +6x = 44cm

22x = 44cm

x= 2cm

So,

Sides of the triangle are 18cm, 14cm and 12cm

Its area cannot be find
