Answer:

$A = 212.1 \text{ cm}^2$

Explanation:

We can identify the bases of the trapezoid as:

9cm and 21.3 cm

(notice how they are parallel)

We know the height is 14 cm.

Using these values, we can solve for the trapezoid's area.

$A = (1)/(2)(b_1 + b_2) \cdot h$

↓ plugging in the values

$A = (1)/(2)(9 + 21.3) \cdot 14$

↓ simplifying the parentheses

$A = (1)/(2)(30.3) \cdot 14$

↓ multiplying 14 and (1/2)

$A = 7 \cdot 30.3$

↓ multiplying

$A = 212.1 \text{ cm}^2$
