Answer: \(307.5\ in.^2\)

Step-by-step explanation:

The area of trapezoid is given by :-

\(\text{Area}=\dfrac{1}{2}(a+b)h\), where a and b area the bases and h is height of the trapezoid.

Given: The length of the bases are 20 in. and 29.2 in. cm.

The height of the trapezoid = 12.5 in.

Now, the area of a trapezoid will be:-

\(\text{Area}=\dfrac{1}{2}(20+29.2)(12.5)\\\\\Rightarrow\text{Area}=307.5\ in.^2\)

Hence, the area of a trapezoid  = \(307.5\ in.^2\)
