1) Perimeter of a square = 4*|length of a side of a square|
Perimeter of the square = 4*(4x-1)
2) Perimeter of a rectangle = 2*Length +2*Wide
Perimeter of the rectangle = 2*(2x+1) + 2*(x+2)
3) Perimeter of the square = Perimeter of the rectangle
4*(4x-1) = 2*(2x+1) + 2*(x+2)
16x - 4 = 4x + 2 + 2x + 4
10x = 10
x=1
