The area is 48 square inches and the original dimensions are 6 by 8 inches.
Step-by-step explanation:
Total area = (6 x 5 + 3 x 6) sq.in. = 48 sq. in.
The original size of the (rectangular) paper must have been 6 by 8 inches. The two pieces share a side of length 6, so that's the first dimension. The sum of their other sides gives the second dimension: 3+5=8 inches.
