Video Solution

Solution Steps

00:00 Determine how many tiles Joseph needs to fill the pool
00:03 Apply the formula for calculating the area of a rectangle
00:06 Side(5) X side(10)
00:09 This is the area of one tile, now let's see how many are needed for the pool
00:13 Divide the pool area by the area of one tile
00:16 This is the required number of tiles and the solution to the problem

Step-by-Step Solution

First, let's calculate the area of the tile by multiplying length and width:

10×5=50 10\times5=50

Now let's calculate how many tiles fit in the given pool area - 850 cm²:

850:50=17 850:50=17

Therefore, Joseph needs 17 tiles in total.
