Answer:

D) 13.5 cm squared (13.5 cm²)

Explanation:

In this question, it's asking you to find the area of the rectangle.

In order to solve this question, we need to use the helpful information that the question gives us.

Important Information:

  • Length is 3 cm
  • Width is 4.5 cm

With the information above, we can solve the problem.

To find the area of the rectangle, we would need to multiply the length times the width.

length × width (or l × w)

We know that the length is 3 and the width is 4.5, so we would multiply 3 and 4.5 in order to get the area of the rectangle.


3 * 4.5=13.5

When you're done multiplying, you should get 13.5. With the unit, it would be 13.5 cm² (area of a rectangle is always squared).

This means that the area of the rectangle is 13.5 cm²

I hope this helped you out.

Good luck on your academics.

Have a fantastic day!
