1. if the perimeter of a square is 480 feet, then what is the area? 2. if the perimeter of a square is 1,000 feet, then what is the area? 3. if the perimeter of a square is 6 miles, then what is the area?

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
