Square A has an area of 81 square centimeters. Square B has a perimeter of 32 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? Options
A) 17/64 B) 17/81 C) 16/25 D) 3/5 E) 6/25
I guess it's mean that square B is placed within square Aentirely.   Since, the perimeter of B is 32, then its side is 32/4=

8 and the area is 4^2=64;   Empty space between the squares is 81-64=

<output>17</output>
17 square centimeters, so if a random point is in this area then it won't be within square B: P=favorable/total=17/81.   Answer: 17/81
<result>B</result>
