Question

the sides of a triangle ate 3x+1,4x+2 and 5x find the perimeter of the triangle

Answer 1

=3x+1+4x+2+5x
=12x+3
12x=3
x=3÷12
x=0.5
3x+1=3×0.5+1=2.5
4x+2=4×0.5+2=4
5x=5×0.5=2.5
perimeter of triangle= 2.5+4+2.5
=9squnit

Answer 2

Given :

The sides of a triangle ate 3x+1,4x+2 and 5x

To Find :

Find the perimeter of the triangle

Solution:

Sides of triangle are :

First side = 3x+1

Second side = 4x+2

Third side = 5x

Perimeter of side = Sum of all sides

Perimeter of side = 3x+1+4x+2+5x=12x+3

Hence The perimeter of triangle is 12x+3
