Calculate the indicated areas. All data are accurate to at least two significant digits.

Using aerial photography, the widths of an area burned by a forest fire were measured at 0.5-mi intervals, as shown in the following table:

Distance (mi) Width (mi) 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5


Determine the area burned by the fire by using the trapezoidal rule.

Distance (mi) Width (mi) 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 0.6 2.2 4.7 3.11 3.6 1.6 2.2 1.5 0.8
