1-37.

The area represents distance traveled (or displacement) between *x* = 0 and *x* = *t*.

The shape is a trapezoid.

Height is horizontal, so it represents time, in hours. Evaluate the area of a trapezoid. Simplify the units.

Find A (20*x* + 30, 0 ≤ *x* ≤ 2).

Use the eTool below to set values for *t*.
