Ответ:
( 9x - 18 ) square inches
Step-by-step explanation:
Data provided in the question:
Side of the square piece of gift wrapping paper = x inches
Now,
According to the question:
He cut 6 inches off the right side of the paper and discarded the rectangular scrap
Therefore,
Dimension of the scrap formed will be 6x square inches
The dimensions of the paper left
Top width will be ( x - 6 ) and the right width will be x
Next he cut 3 inches off the top of the paper and again discarded the rectangular scrap
Therefore,
Dimension of the scrap will be
( x - 6 ) long wide and 3 inches wide
Hence,
The area of the scraps will be
⇒ 6x + 3(x - 6)
⇒ 6x + 3x - 18
⇒ ( 9x - 18 ) square inches
