Question

the perimeter of triangle is 120 cm and its sides are in ratio 5 ratio 12 ratio 30 find area of triangle​

Answer 1

Answer:

Step-by-step explanation:

Perimeter oF Triangle = 10 cm

Ratio of sides =5:12:13

Let the sides be 5x, 12x, 13x

To Permieter 5x+12x+13X = 120 Cm ⇒ x=4cm

So Sides are = 5x4 = 20cm Simlarly other Sides are 48cm and 52cm

Area of Triangle = √S(S-a)(S-b) S-c)

S = 120/2 = 60cm

Area of Triangle = √60(60-20)(60-48)(60-52)

On SImplification

Area Of Triangle = 480cm^2
