Answer:
/sqrt(9) would be rational. the square root of 9 is 3, 3x3 is 9. a irrational number cannot be written as a simple fraction.
B makes the most sense. Try it out and let me know!!
P = 2(L + W)
P = 360
L = 5W
360 = 2(5W + W)
360 = 2(6W)
360 = 12W
360/12 = W
30 = W <=== width
L = 5W
L = 5(30)
L = 150 <=== length
S is greater than or equal to 201 1/3
