Answer:

Explanation:
Given
See attachment for complete question
Required: The base area.
From the question, we have the initial dimensions to be:


h inch were removed from each corner to form the new base. So, the dimension of the new base is:




The area of the base is calculated by multiplying the base dimensions

![Area = [Length - 2h] * [Width - 2h]](https://img.qammunity.org/2022/formulas/mathematics/high-school/54vhvlzffmm1hqmz0yxitpjho8ymgbcve7.png)
![Area = [12 - 2h] * [12 - 2h]](https://img.qammunity.org/2022/formulas/mathematics/high-school/qcotyj0bnpij8mnt9632f5y5nuqjgt9rpp.png)
Expand
![Area = 12[12 - 2h] -2h [12 - 2h]](https://img.qammunity.org/2022/formulas/mathematics/high-school/lkzvohfbt2wkij8kyhtihmg0rucuvtzamc.png)


Rewrite as:
