The sides of a triangle are in ratio 1:3:4 .If the perimeter of a triangle is 96 cm then find the length of the sides of a triangle ?

$\Large\green{\underline{\underline{\bf{To\:find}}}}$

find the length of the sides of a triangle

$\Large\green{\underline{\underline{\bf{Solution}}}}$

Let the side be x , 3x and 4x

According to the question

Perimeter of triangle = 96cm

=> x + 3x + 4x = 96

=> 8x = 96

=> x = 96/8 = 12cm

Hence ,

Side of triangle are

• x = 12cm
• 3x = 3×12 = 36cm
• 4x = 4×12 = 48cm
