Chapter 11.2, Problem 16PPS

To determine

To find: The area of the identified shape.

Answer to Problem 16PPS

The area of the shape is $9.89{\text{microns}}^2$ .

Explanation of Solution

Given:

The given diagram is shown in Figure 1

  

Figure 1

Calculation:

The given shape is the shape of the trapezoid doubled.

Consider the area of the trapezoidis,

  $A=\frac{b_1+b_2}{2}h$

Then,

  $\begin{array}{c}2A=2\left[\frac{1.2+3.1}{2}\left(2.3\right)\right]\\ =\frac{\left(4.3\right)\left(2.3\right)}{2}\\ =9.89{\text{microns}}^2\end{array}$
