How I can solve this qustions???

Last night Taliban attacked a police station. Afghan National Police fought them and repelled the attack by killing all of them. However, after the attack, Police forces noticed a strange pattern of tiny holes in the station’s wall. They decide to cover these holes by a kind of bulletproof sheet metal temporarily. These sheets are only in square shape in different sizes, so they should use them to cover near t o each other holes. Therefore, they first disjoint the holes to N parts based on their distance from each other. Then calculate and select appropriate sheet metal to cover each part. Write a program to find the area of the smallest square that will cover

Example: 3

-1 , -1

1 , 1

1 , 2

Output : 6.50

Or

4

5 , 2

5 , -2

-5 , 2

-5 , -2

Output : 98.00
