Question

The area of a triangle is 150 cm square and its sides are in the ratio 3 : 4 : 5. What is its

Answer 1

Step-by-step explanation:

perimeter:

Let coefficient of ratios be X

a = 3x

b = 4x

c = 5x

Using Heron's Formula,

s = (3+4+5)x/2 = 12x/2 = 6x

Now,

a = 5*3 = 15 cm

b = 5*4 = 20 cm

c = 5*5 = 25 cm

Perimeter = 15+20+25 = 60 cm
