\( \left. \begin{array} { l l } { a 1 = 85 cm } & { a 2 = 33 cm } \\ { b 1 = 56.48 cm } & { b 2 = 56.23 cm } \\ { h = 50 cm } & { } \end{array} \right. \)

Did you know that the dimensions you've provided could pertain to a variety of geometric shapes? For example, they might be the bases and height of a trapezoid! The formula for the area of a trapezoid is \( A = \frac{1}{2} (a_1 + a_2) \cdot h \). Plugging your values into the formula can help you determine the area, and it all starts with those dimensions! Now, when working with such formulas, it's easy to make small mistakes that can lead to incorrect results—like misplacing decimal points or mixing up units! Always double-check your calculations, and remember to keep track of your units; for example, if you're calculating area in square centimeters, ensure that all your dimensions are in centimeters, just like you’ve done here!
