The dispensing unit worth today: $21,000
Step-by-step explanation:
If we assume that a year has elapsed since the dispensing unit was purchased, then we know that it has lost 25% of its initial value.

If the side lengths of the rectangle are 3 and 12, then the area, length times width, is 36.
If the area of the square is equivalent to the area of the rectangle, then
which is the formula for the area of a square. Take the square root of 36 to get that each side of the square is 6 inches long.
Since a square has 4 sides, we get that the perimeter of that square is 4 * 6 which is 24 inches.
