Explanation:

COmplete Question is in attached image.

Eric will want to buy fencing that is sum of perimeter of the square border outside and hexagon inside.

Perimeter is the sum of all sides.

Perimeter of hexagon is sum of 6 sides.

Each side is 5, so

Perimeter of Hexagon = 5 + 5 + 5 + 5 +5 +5 = 30

Now,

Perimeter of Square is sum of all 4 sides measuring 12 each, so

Perimeter of Square = 12 + 12 + 12 + 12 = 48

Total amount of fencing needed = 30 + 48 = 78
