Square A has an area of 121 square centimeters. Square B has a perimeter of 16 centimeters. If square B is placed within square A and a random point is chosen within square A, what is the probability the point is not within square B? Select the correct option
A) 9/25	B) 1/5	C) 16/121	D) 105/121	E) 6/25
I guess it's mean that square B is placed within square Aentirely.   Since, the perimeter of B is 16, then its side is 16/4=

4 and the area is 4^2=16;   Empty space between the squares is 121-16=

<output>105</output>
105 square centimeters, so if a random point is in this area then it won't be within square B: P=favorable/total=105/121.   Answer: 105/121.
