The area of the rectangular tank is 6 dm2. How to find its possible width and length dimensions?

We will proceed from the fact that the length and width of the base of a given rectangular tank are expressed as an integer number of decimeters, since otherwise this problem would have an infinite set of solutions.

Since at the base of this tank lies a rectangle, the area of which can be calculated by multiplying the length and width of this rectangle and, according to the problem statement, this area is 6 dm ^ 2, then the possible pairs of values for its length and width are as follows: 6 dm; 1 dm and 3 dm; 2 dm.

Answer: 6 dm; 1 dm and 3 dm; 2 dm.
