Answer:
80 yd^2
Step-by-step explanation:
Since the formula for squares is s^2, we can use this to set up an equation, which is
s^2=400
If we square root this, we get
s=20
The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2
Answer:
x= - 18/7 - 1/7y, y
or if you are solving for y= -18-7x, x

Step-by-step explanation:
See image below:)

Multiply both sides by 2.54.


Multiply both sides by x.
x = 60.96
Hence, Aaron needs 60.96 centimeters of wire.
