Answer: 40.5 square feet
Step-by-step explanation:
Given : Zhi needs new flooring for her two laundry rooms.each room is 4.5 feet long and 4.5 feet wide .
We assume that the room is rectangular in shape .
Area of rectangle = Length x width
Then area of one laundry room = 4.5 feet x 4.5 feet = 20.25 square feet
Area of two laundry room = 2 x 20.25 = 40.5 square feet.
Hence, The flooring need to cover a total of <u>40.5 square feet</u> of area.
To find the value of 1, you would find what place it is in. It is in the 100,000 place.
Next, you would make all the numbers after it 0. 100,000.
The value of 1 is 100,000.
