| 1. Let’s denote one part by x.
2. Determine the length of the smaller base of the trapezoid:
2 * x = 2x.
3. Find out the length of the larger base of the trapezoid:
3 * x = 3x.
4. Since the middle line of the trapezoid is 25, compose and solve the equation:
(2x + 3x) / 2 = 25;
5x = 25 * 2;
5x = 50;
x = 50: 5;
x = 10.
5. One part is equal to x = 10.
6. What is the length of the smaller base of the trapezoid?
2 * 10 = 20.
Answer: The length of the smaller base of the trapezoid is 20.
