Step-by-step explanation:
28 x 16.387 = <u>458.838</u>
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
