Question

the sides of equilateral 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

Step-by-step explanation:

perimeter of equilateral triangle =x-2+2x+x+2=16

4x=16

x=16/4=4

side of equilateral triangle x-2=4-2=2

2x=2×4=8

x+2=4+2=6

it's not equilateral triangle because their sides are not equal
