Question

the sides of a triangle are in the ratio 5: 12:13 and its perimeteris 150 cm . find the area of triangle

Answer 1

Hey Friend ☺

Sides of the triangle are in ratio 5 : 12 : 13
Let the common multiple be x

So sides are 5x , 12x & 13x

Perimeter of the triangle = sum of all sides

》150 = 5x + 12x + 13x

》150 = 30x

》x = 150/30

》x = 5

So the sides are 25 cm , 60 cm & 65 cm

If we observe carefully the it is a Pythagoras triplet

So the triangle is right angled triangle

So area = 1/2 × product of sides forming right angle

= 1/2 × 25 × 60

= 25 × 30

= 750 cm^2

So the area of the triangle is 750 cm^2

Hope it helps you ..!!
