Step-by-step explanation:
80 - 3.50x ........ (i)
70 - 3x ..............(ii)
Set them equal;

Step-by-step explanation:
we know that
![1\ ft=0.3048\ m](https://tex.z-dn.net/?f=1%5C%20ft%3D0.3048%5C%20m)
we have
![1,350\ ft^{2}](https://tex.z-dn.net/?f=1%2C350%5C%20ft%5E%7B2%7D)
Convert to ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
![1,350\ ft^{2}=1,350(0.3048)^{2}=125.42\ m^{2}](https://tex.z-dn.net/?f=1%2C350%5C%20ft%5E%7B2%7D%3D1%2C350%280.3048%29%5E%7B2%7D%3D125.42%5C%20m%5E%7B2%7D)
