Greece

  • The flag of Greece has 5 blue stripes and 4 white stripes.
  • Each stripe has width 40.
  • Note that we let the computer do the arithmetic. Each stripe should

be 80 pixels below the previous one.

  • The expression 20+i*80 - where i is 0, 1, 2, 3, 4 gives the

height of the middle of each blue stripe.

  • The expression 60+i*80 - where i is 0, 1, 2, 3 gives the

height of the middle of each white stripe.

  • You must include another two blue stripes and four white stripes.
