Answer:
Length: 19 feet
Width: 10 feet
Area: 190 feet![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
Step-by-step explanation:
This is a question about ratio.
Length: let
be the actual length.
![15.2 : x = 4 : 60](https://tex.z-dn.net/?f=15.2%20%3A%20x%20%3D%204%20%3A%2060)
![x = 19](https://tex.z-dn.net/?f=x%20%3D%2019%20)
Width: let
be the actual width.
![8 : y = 4 : 60](https://tex.z-dn.net/?f=8%20%3A%20y%20%3D%204%20%3A%2060)
![y = 10](https://tex.z-dn.net/?f=y%20%3D%2010)
Area: A = xy
![19 * 10 = 190](https://tex.z-dn.net/?f=%2019%20%2A%2010%20%3D%20190)
