Question

suppose the length of each card in the example problem is shortened to 1/4 meter.Will the area of each card now be greater or less than 1/20 square meter? Explain​

Answer 1

less than 1/20 square meter

Explanation:

The area of each card will be less than 1/20 square meter.

Reason: A card that is 1/10 m wide and 1/2 m long has an area of 1/20 square meter. By making the length of the card half of what it was but not changing the width, the area of each card is 1/2 of what it was, so the area is now smaller. The new area is less than 1/20 square meter.
