The three sides of a triangle are (x+5), (4x-y) and (y+2) centimetres in length. If the triangle is equilateral, find its perimeter.

The lengths of the sides of a triangle are 2x+(y)/(2) , (5x)/(3)+y+(1)/(2) and (2)/(3)x+2y+(5)/(2) .If the triangle is equilateral, then its perimeter is

The length of three sides of a triangle are (x+4)cm, (2x+1)cm, and (4x-8)cm, find the perimeter of the triangle.
