Make this easier:
First, we need to find the dimensions of the storage room. Since the area of the storage room is 144 square feet and the length of the basement is 48 feet, we can find the width of the storage room by dividing the area by the length.
Width of storage room = Area of storage room / Length of basement
Width of storage room = 144 ft / 48 ft
Width of storage room = 3 ft
So, the dimensions of the storage room are 48 ft by 3 ft.
Next, we can find the area and perimeter of the table tennis room by subtracting the area and length of the storage room from the total area and length of the basement.
Area of table tennis room = Total area - Area of storage room
Area of table tennis room = 48 ft * 12 ft - 144 ft
Area of table tennis room = 576 ft - 144 ft
Area of table tennis room = 432 ft
Perimeter of table tennis room = 2(length + width)
Perimeter of table tennis room = 2(48 ft + 12 ft)
Perimeter of table tennis room = 2(60 ft)
Perimeter of table tennis room = 120 ft
Therefore, the area of the table tennis room is 432 square feet and the perimeter is 120 feet.
To find the dimensions of the storage room, divide the area of the storage room by the length of the basement to get the width. The width of the storage room is 3 feet. The dimensions of the storage room are 48 feet by 3 feet.
To find the area of the table tennis room, subtract the area of the storage room from the total area of the basement. The area of the table tennis room is 432 square feet.
To find the perimeter of the table tennis room, add the length and width of the room, multiply by 2. The perimeter of the table tennis room is 120 feet.
