Given:
Area of rectangle =
sq. feet.
Width of the mirror =
feet.
To find:
Whether it will fit on the wall whose length is 5 foot.
Solution:
We know that, area of a rectangle is
![Area=length\times width](https://tex.z-dn.net/?f=Area%3Dlength%5Ctimes%20width)
![\dfrac{Area}{width}=length](https://tex.z-dn.net/?f=%5Cdfrac%7BArea%7D%7Bwidth%7D%3Dlength)
Substituting the given values, we get
![Length=\dfrac{15\dfrac{7}{16}}{3\dfrac{1}{4}}](https://tex.z-dn.net/?f=Length%3D%5Cdfrac%7B15%5Cdfrac%7B7%7D%7B16%7D%7D%7B3%5Cdfrac%7B1%7D%7B4%7D%7D)
![Length=\dfrac{\dfrac{15\times 16+7}{16}}{\dfrac{3\times 4+1}{4}}](https://tex.z-dn.net/?f=Length%3D%5Cdfrac%7B%5Cdfrac%7B15%5Ctimes%2016%2B7%7D%7B16%7D%7D%7B%5Cdfrac%7B3%5Ctimes%204%2B1%7D%7B4%7D%7D)
![Length=\dfrac{\dfrac{240+7}{16}}{\dfrac{12+1}{4}}](https://tex.z-dn.net/?f=Length%3D%5Cdfrac%7B%5Cdfrac%7B240%2B7%7D%7B16%7D%7D%7B%5Cdfrac%7B12%2B1%7D%7B4%7D%7D)
![Length=\dfrac{\dfrac{247}{16}}{\dfrac{13}{4}}](https://tex.z-dn.net/?f=Length%3D%5Cdfrac%7B%5Cdfrac%7B247%7D%7B16%7D%7D%7B%5Cdfrac%7B13%7D%7B4%7D%7D)
![Length=\dfrac{247}{16}\times \dfrac{4}{13}](https://tex.z-dn.net/?f=Length%3D%5Cdfrac%7B247%7D%7B16%7D%5Ctimes%20%5Cdfrac%7B4%7D%7B13%7D)
![Length=4.75 ](https://tex.z-dn.net/?f=Length%3D4.75%0A)
So, length of mirror is 4.75 feet which is less than 5 feet.
Therefore, the mirror will fit on the wall.
We shall see how much percentage of the original price was the price discounted and it will show the percentage decreased
325x/100=123.50
325x=12350
X=12350/325
X=38
hope u found this answer helpful
