![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
Step-by-step explanation:
Area is found by mulitplying width and height.
![A=7.5(5)\\](https://tex.z-dn.net/?f=A%3D7.5%285%29%5C%5C)
in
The ratio is 0.5in : 1ft, so if you multiply that ratio to the answer, you should get the answer in feet.
in x
![=75](https://tex.z-dn.net/?f=%3D75)
![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
Let x = the length of a side of the square (m).
The area is
A = x²
The perimeter is
P = 4x
The rate of change of P with respect to x is
P'(x) = 4 (independent of x)
When A = 49 m², then x = 7 m.
The rate of P is 4.
