Answer:
x = 11.02 inch by y = 7.35 inch
Explanation:
Let the width of the print be = x
Then the width of the page is x + (1.5+1.5) = x + 3
Let the height of the print be = y
Then the height of the page is y + (1+1) = y + 2
Given the area of the print is 81 square inches
That means, xy = 81
Therefore, y = ![\frac{81}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B81%7D%7Bx%7D)
Therefore, the area of the page is
A = (x + 3)(y + 2)
= (x + 3)(
+ 2)
Now for least amount of paper to be used,
![\frac{dA}{dx}=(x+3)(\frac{81}{x}+2)](https://tex.z-dn.net/?f=%5Cfrac%7BdA%7D%7Bdx%7D%3D%28x%2B3%29%28%5Cfrac%7B81%7D%7Bx%7D%2B2%29)
![\frac{dA}{dx}= \left (\frac{81}{x}+2 \right )+\left ( x+3 \right )\left ( -\frac{81}{x^{2}} \right )=0](https://tex.z-dn.net/?f=%5Cfrac%7BdA%7D%7Bdx%7D%3D%20%5Cleft%20%28%5Cfrac%7B81%7D%7Bx%7D%2B2%20%20%5Cright%20%29%2B%5Cleft%20%28%20x%2B3%20%5Cright%20%29%5Cleft%20%28%20-%5Cfrac%7B81%7D%7Bx%5E%7B2%7D%7D%20%5Cright%20%29%3D0)
![\frac{81+2x}{x}=\frac{(x+3)(81)}{x^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B81%2B2x%7D%7Bx%7D%3D%5Cfrac%7B%28x%2B3%29%2881%29%7D%7Bx%5E%7B2%7D%7D)
![81x+2x^{2}=81x+81\times 3](https://tex.z-dn.net/?f=81x%2B2x%5E%7B2%7D%3D81x%2B81%5Ctimes%203)
![2x^{2}=243](https://tex.z-dn.net/?f=2x%5E%7B2%7D%3D243)
x = 11.02 inch
Now y = ![\frac{81}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B81%7D%7Bx%7D)
= ![\frac{81}{11.02}](https://tex.z-dn.net/?f=%5Cfrac%7B81%7D%7B11.02%7D)
= 7.35 inch
Therefore the dimensions of thr page for the least amount of paper is x = 11.02 inch by y = 7.35 inch
