A rectangle is shown in the figure with two side lengths labeled.
Which choice is the area of the rectangle, in square units?
For an area-and-volume question involving a rectangle, focus on reading the needed dimensions directly from the figure. Then apply the basic formula (multiply the two adjacent side lengths) and pick the matching choice.
Hints
Identify the rectangle’s side lengths
Look at the two labeled sides of the rectangle in the figure.
Recall the area formula
For a rectangle, area equals the product of two adjacent side lengths.
Multiply
Multiply the two labeled side lengths to get the area in square units.

Use the value shown by Desmos as the rectangle’s area, then match it to the answer choices.
Step-by-step Explanation
Set up the area expression
From the figure, the rectangle’s adjacent side lengths are 13 units and 5 units.
Use to write .
Compute the area
, so the area of the rectangle is 65 square units.
