Joseph is building a pool.
He buys tiles with sides measuring 10 cm by 5 cm.
The size of Joseph's pool is 850 cm².
How many tiles does Joseph need to complete the pool?
First, let's calculate the area of the tile by multiplying length and width:
Now let's calculate how many tiles fit in the given pool area - 850 cm²:
Therefore, Joseph needs 17 tiles in total.
Look at the rectangle below.
Side DC has a length of 1.5 cm and side AD has a length of 9.5 cm.
What is the perimeter of the rectangle?
You need to know how much space each tile covers before you can figure out how many fit in the pool! Think of it like puzzle pieces - you need to know the size of each piece first.
In real life, you'd need to round up to the next whole number since you can't buy part of a tile. But for math problems, give the exact answer unless told otherwise.
Absolutely! Multiply your answer by the tile area: 17 × 50 = 850 cm². If you get the original pool area, you're correct!
Then you'd get a decimal or fraction answer. This means some tiles would need to be cut to fit perfectly. Always show your exact calculation first.
Not for this problem! You only need the total area. Whether the pool is square, rectangular, or another shape doesn't matter - just divide total area by tile area.
