Answer:


\huge\boxed{\sf Area \ of \ border = 104\ in.\²}

Explanation:

Area of larger rectangle:

= Length * Width

= 18 * 12

= 216 in.²

Area of smaller triangle:

Length = 12 - 2 - 2 = 8 in.

Width = 18 - 2 - 2 = 14 in.

= Length * Width

= 8 * 14

= 112 in.²

Area of shaded region:

= 216 - 112

= 104 in.²


\rule[225]{225}{2}

Hope this helped!
