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.
Answer: 4
Answer:
<h2>-4/3</h2>
Step-by-step explanation:
<h3>Step 1: Divide</h3>

<h3>Step 2: Answer</h3>
x = -4/3
<h3>Step 3: Check</h3>
10/3 = -4/3 / -5/2
3.3 = 3.3✔️
<h3>Step 4: Verified Answer</h3>
x = -4/3
I'm always happy to help :)
Multiply the previous number by 4.
