A=LW
L=W-4
A=252
sub W-4 for L
A=(W-4)(W)
252=(W-4)(W)
252=W²-4W
minus 252 both sides
0=W²-4W-252
what 2 numbers multiply to get -252 and add to get -4
-18 and 14
0=(W-18)(W+14)
set to zero
W-18=0
W=18
W+14=0
W=-14
false, we can't have negative width
Width=18
L=W-4
L=18-4
L=14
length=14cm
width=18cm

Answer:
6647.6 liters
Step-by-step explanation:
The volume of a cylinder with end area r and length (or height) h is
V = πr²h
If we substitute 2.3 m for r and 400 m for h, we get:
V = π(2.3 m)²(400 m) = 6647.6 m³ or 6647.6 liters
