John bought a rectangle door mat that was 1/2 meter long and 3/10 meter wide. what is the area of the door mat

Hello there!

To start, the area of a rectangle is found by multiplying together its length and width.

In this case, the length is 1/2 and the width is 3/10, so you can represent the area using this expression:
×

Now, multiply straight across, the numerator times the numerator over the denominator times the denominator.

This would result in your final answer, .

Therefore, the area of the rectangular door mat would be meters squared.
