The answer is:
The dimensions of the paper for Gift C, are: 25" x 12"
and its area is:
![GiftCArea=300inch^{2}](/tpl/images/0488/3144/a14d0.png)
Why?To solve the problem, we need to calculate the total area of the remaining paper, and then, subtract it from the paper used for the gift A and B.
We know that:
Now, the paper for Gift C will be:
From the statement we know that the dimenstions of the remaining paper are 25" x 45", so calculating the area we have:
Now, calculating the area of the paper for Gift A and B, we have:
Then, calculating the paper for Gift C, we have:
Therefore, calculating the dimensions of the paper for Gift C, knowing the height of the paper (25inches), we have::
Hence, the dimensions of the paper for Gift C, are: 25" x 12".
Have a nice day!
