The bottom of the pool has a rectangular shape, It was laid out with square tiles with sides of 2 dm, A total of 31,250 tiles were required, Find the length of the pool if the width is 25 m.

It is known that the bottom of the pool, which has the shape of a rectangle, was tiled.

These tiles are in the shape of a square and their length is 2 dm.

Let’s calculate the area of one such tile:

S = a² = 2² = 4 dm².

Let’s calculate the area of the pool bottom by multiplying the area of one tile by the amount it took to lay the entire bottom:

4 * 31250 = 125000 dm² = 1250 m².

Let’s calculate the length of the pool, given that its width is 25 m:

b = S / a = 1250/25 = 50 m.

Answer: the length of the pool is 50 meters.
