Answer:
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
Step-by-step explanation:
Let the scale be
and the dimensions of the rectangle being 4 inches and 5 inches, respectively. The scale (
), measured in inches per feet, is equivalent to the following rational number:
![r = \frac{4\,in}{5\,ft}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B4%5C%2Cin%7D%7B5%5C%2Cft%7D)
We can convert each length by dividing it by scale factor. That is:
Length
![l' = \frac{16\,in}{\frac{4\,in}{5\,ft} }](https://tex.z-dn.net/?f=l%27%20%3D%20%5Cfrac%7B16%5C%2Cin%7D%7B%5Cfrac%7B4%5C%2Cin%7D%7B5%5C%2Cft%7D%20%7D)
![l' = 20\,ft](https://tex.z-dn.net/?f=l%27%20%3D%2020%5C%2Cft)
Width
![w' = \frac{25\,in}{\frac{4\,in}{5\,ft} }](https://tex.z-dn.net/?f=w%27%20%3D%20%5Cfrac%7B25%5C%2Cin%7D%7B%5Cfrac%7B4%5C%2Cin%7D%7B5%5C%2Cft%7D%20%7D)
![w' = 31.25\,ft](https://tex.z-dn.net/?f=w%27%20%3D%2031.25%5C%2Cft)
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
Step-by-step explanation:
Amount of money spend in 1 day = x
So, amount of money spend in 7 days = (7x)
⇒ Amount of money spend in 1 week = (7x)
Amount of money saved in 1 week = y
∴ Income in 1 week = (7x + y)
So, income in 3 weeks = [3 x (7x + y)]
= (21x + 3y)
