To determine the perimeter of the second room, we first need to calculate the area of the first room and then use the information provided about the combined area of the two rooms.

The area of the first room can be calculated using the formula for area, which is length multiplied by width. In this case, the first room has a width of 10 feet and a length of 6 feet. Therefore:

Area of the first room = Length × Width = 6 feet × 10 feet = 60 square feet.

Next, we know that the combined area of the two adjacent rooms is 160 square feet. To find the area of the second room, subtract the area of the first room from the combined area:

Area of the second room = Combined area - Area of the first room

= 160 square feet - 60 square feet

= 100 square feet.

Now that we know the area of the second room is 100 square feet, we can express the dimensions of this room. The actual dimensions (length and width) are not specified, so we can assume typical dimensions that could fit this area, like 10 feet by 10 feet or 20 feet by 5 feet, etc.

However, regardless of
