The length of the side of a square is represented by x+2. The length of the side of an equilateral triangle is 2x. If the square and the equilateral triangle have equal perimeter, then the value of x is _______

• perimeter of square=4(x+2) & Perimeter of triangle=3(2x)
  According to condition both are equal -> 4x+8=6x gives x=4

• parameter of equilateral triangle = 3a = 3*2x=6x.
  parameter of square = 4a = 4*(x+2) = 4x+8.
  6x=4x+8 => 2x=8 => x=4.

• Square =4a => 4(x+2) => 4x+8
  Equilateral triangle = 3(2x) =>6x
  4x+8 = 6x
  x=4
