Let the shorter base be ( b ) and the longer base be ( 3b ). The height is given as the average of the two bases, which is ( \frac{b + 3b}{2} = 2b ). The area of the trapezoid is given by the formula ( \text{Area} = \frac{1}{2} \times (b + 3b) \times \text{height} ), leading to ( 112 = \frac{1}{2} \times 4b \times 2b ). Simplifying gives ( 112 = 4b^2 ), so ( b^2 = 28 ) and ( b = \sqrt{28} = 2\sqrt{7} ). Therefore, the longer base is ( 3b = 6\sqrt{7} ) yards.
The answer is 1 + 5v.

The commutative property is a fundamental principle in mathematics that states the order of numbers in an operation does not affect the result. It applies to addition and multiplication; for example, (a + b = b + a) and (a \times b = b \times a). This property does not hold for subtraction or division, where changing the order can lead to different results. Understanding this property is essential for simplifying and solving mathematical expressions.
