Answer 1

The area will decrease by 1% of the original area.

Step-by-step explanation:

Since we have given that

Length of rectangle is increased by 10%

Width of rectangle is decreased by 10%

we need to find the area will change by what percentage.

So, percentage change in area would be

-1%

Hence, the area will decrease by 1% of the original area.
