One base of a trapezoid is 5 cm larger than the other, and the middle line of a trapezoid is 16 cm. What are the bases of a trapezoid?

The middle line of a trapezoid is calculated by the formula: (base1 + base2): 2
Let base1 be smaller and equal to x. Then base2 is x + 5. Substitute the result into the formula for finding the midline of a trapezoid.
Let’s make the equation:
(x + x + 5): 2 = 16
2x + 5 = 16 * 2
2x + 5 = 32
2x = 32-5
2x = 27
x = 13.5
So base1 is 13.5. Find the foundation2 by substituting 13.5 into the expression x + 5: 13.5 + 5 = 18.5
