Final answer:
The front of the cottage facing the lake can be a maximum of 85 feet.
Step-by-step explanation:
To determine how long the cottage front facing the lake may be, we need to consider the building code restriction. According to the code, a building must be no closer than 25 feet to the lot line. In this case, the lot has 110 feet of frontage on the lake. Therefore, the front of the cottage facing the lake can be a maximum of 110 feet minus 25 feet, or 85 feet.
