<span>Perimeter =2w+2L= 520.
We can solve this by understanding that the area is maximized by a square
Therefore L=w.
p=2w+2w=520=4w
w=130
Area
A=wL=130(130)= 16900 square yards</span>
1.a)add
B) substract
C) multiply
D) one
2) 1002=1.002×10^3
3)2.8×10^-3 < 2.5×10^-2 < 1.2×103 <4×103
So here. I don't know how to explain so-
1. incorrect
2. correct
3. incorrect (?)
