Answer:
The carpet is the one that has an area of 21/50 square meters.
Explanation:
To find the area of the carpet, we need to multiply the length and width of the carpet. The length of the carpet is 7/10 of a meter and the width of the carpet is 3/5 of a meter.
So, the area of the carpet is:
(7/10) x (3/5) = (21/50) square meters
Therefore, the correct model that shows the area of the carpet is the one that has an area of 21/50 square meters.
