The pool is rectangular, 50 m long and divided into 6 lanes, each 2.5 m wide. Find the area of this pool.

Let’s find out how many meters the second size of the designated pool will be equivalent to, when it is known, in accordance with the data from the conditions of our assignment, that the width of each of the six tracks in it is 2.5 meters:
2.5 * 6 = 15.
Let’s calculate what the bottom area of the designated pool will equal, when it is known, in accordance with the data from the conditions of our assignment, that its length is fifty meters:
50 * 15 = 750.
Answer: The area of the bottom of the designated pool will be equal to seven hundred and fifty m2.
