Answer:

The dimension has to be reduced by two inches.

Step-by-step explanation:

Given that the dimensions are: 6 by 8 inches which means that the area is 48 square inches.

Let x be the amount to make a new photo which is half of the area that means

The new dimensions will be: (8-x) by (6-x) and as the area is half

The area of new photo will be: 48/2 = 24

Putting it mathematically (Look at the solution above).

Subtracting 12 from both dimensions will make them negative so 12 cannot be the solution.

Hence, the dimensions have to be reduced by 2 inches
