Hi,
I like playing with the numbers. I do it either by playing games or by solving problems containing numbers. I also play to earn money for myself.
I use numbers form my date of birth, my telephone number, my street number, sometimes my house number to play lucky draws and try out my luck to win a jackpot. Sometimes I win and sometimes I loose.
So, I love to play with numbers.
Whenever I win, mostly I chose to take a lump sump amount so that I can immediately invest it in some other work to gain money.

Let X be width <span>of a rectangle, then
(x+8) - </span><span>length
(x+x+8)*2 = 52
x+x+8 = 52/2
2x+8 = 26
2x = 26-8
2x = 18
x = 18/2
x = 9 cm
Answer: 9 cm.</span>
