Question

B) The sides of a triangle are in the ratio 13: 14 15 and its perimeter is 168 cm
Find the area of the triangle.​

Answer 1

Answer:

Perimeter of the triangle = 168 cm

Sum of ratios of sides = 15 + 13 + 14 = 42

Let the first side = (168 × 15)/42 = 60 cm

Second side = (168 × 13)/42 = 52 cm

Third side = (168 × 14)/42 = 56 cm

Now, s = (a + b + c)/2

= (60 + 52 + 56)/2 = 168/2 = 84

area =
