Considering the formulas for the area and the perimeter of the rectangle, the one with the desired measures is given as follows:
a length of 3 units and a width of 4 units.
<h3>What are the area and the perimeter of a rectangle?</h3>
Considering a rectangle of length l and width w, we have that:
For a rectangle with a length of 3 units and a width of 4 units, we have that:
- A = 3 x 4 = 12 square units.
Hence it is the correct option.
