Question

the sides of scalene triangle are x - 2 ,2x and x + 2 cm. if the perimeter of the triangle is 16 cm .find the length of the sides​

Answer 1

Answer:

3.2

Step-by-step explanation:

x-2+2x+x+2=16then we get after cutting +2and-2and after callculating values of x we get 5x=16 and x=3.2

Answer 2

Given,

Perimeter of a scalene triangle = 16cm

The sides = x-2,2x,x+2

Since,

Sum of the sides of a triangle= Perimeter of that triangle

=> x-2+2x+x+2 = 16

=> 4x = 16

=> x = 16/4

=> x = 4cm

1st side = x-2 = 4-2 = 2cm

2nd side = 2x = 2×4 = 8cm

3rd side = x+2 = 4+2 =6cm
