Question 1054264: A family decides to put tiles in the entryway of their home. The entryway has an area of 4 square meters. If each tile is 5 centimeters by 5 centimeters, how many tiles will it take to cover the entryway?
A 4-H Club group is raising pigs to show at the County Fair. Each pig eats 2.8 pounds of grain a day. If the grain costs $7.25 per pound, how much will it cost to feed one pig for 60 days?
Please help me :(

You can put this solution on YOUR website! 1 meter=100cm
1 meter^^2=(100 cm)^2=10,000 cm^2. 4 meters^2=40,000 cm^2
Each tile is 5 cm by 5 cm or 25 cm^2
40,000 cm^2/25 cm^2 per tile --units will be tiles
1600 tiles.
Check
make the entry way 2 m x 2 m
It takes 40 tiles at 5 cm each to cover 200 cm or 2 m
It takes another 40 tiles to cover across 200 cm or 2 m
Multiply those and get 1600 tiles.
