Combine like terms:
Subtract 196 from both sides:
Divide both sides by -3

Area = 38 1/4 = 153/4
Width = 4 1/2 = 9/2
Area = Length x Width
Length = Area/Width
So divide both of them:
So the length is equal to
Width = 4 1/2 = 9/2
Area = Length x Width
Length = Area/Width
So divide both of them:
So the length is equal to
