Answer the given questions about the indicated examples of this section.

In Example 5, change 16.2 in. to 61.2 in. What is the answer?

Data from Example 5

Find the areas of the triangles in Fig. 2.31(a) and Fig. 2.31(b).
Even though the triangles are of different shapes, the base b of each is 16.2 in., and the altitude h of each is 5.75 in. Therefore, the area of each triangle is

A 2 =bh = (16.2)(5.75) = 46.6 in.
