The are of the photo using the given data is 48 square inches. Therefore if we are to re-scale it by 1/2, the new area should be 48(1/2) or 24 square inches.
By distributive property, the factor 1/2 is also applicable to both length and width, thus 6(1/2) in by 8 (1/2) in is also equivalent to 3 in by 4 in. Therefore, the new dimensions of the photo when rescaled by half is 3 in by 4 in.
