leah wants to put square floor tiles that measure one foot on each side in a room that is 9 feet and 9 feet wide.
How many floor tiles will leah need?
is your answer reasonable? explain why
- find the area of the individual square
- find the area of the room
- divide the area of the room by the area of the individual square to find how many floor tiles are needed
i don't inderstand what u mean by when you say
find the area of the individual square
- find the area of the room
- divide the area of the room by the area of the individual square to find how many floor tiles are needed
To find the number of floor tiles Leah will need, we need to calculate the area of the room and then divide it by the area of each individual floor tile.
First, let's calculate the area of the room. The room is 9 feet wide and 9 feet long, so the area can be found by multiplying the width and length:
9 feet * 9 feet = 81 square feet
Next, we need to calculate the area of each floor tile. The tile is square-shaped and measures 1 foot on each side, so the area can be found by squaring the length of one side:
1 foot * 1 foot = 1 square foot
Now, to determine how many tiles Leah will need, we divide the area of the room by the area of each tile:
81 square feet รท 1 square foot = 81 tiles
Therefore, Leah will need 81 floor tiles to cover the room.
To verify if the answer is reasonable, we can do a quick sanity check. Since the room is 9 feet by 9 feet, it has an area of 81 square feet. If each tile also covers an area of 1 square foot, it is logical that Leah would need 81 tiles to completely cover the room. So, the answer seems reasonable.
