Answer :
We know that formula for area of rectangle is A=a*b where a and b are sides of rectangle.
So we can substitute our data to this formula
198=18*b (there is no difference which side we take as a or b)
Now we can just solve simply equation
198=18*b /:18 both sides
198:18=b
b=11 - its the result
So we can substitute our data to this formula
198=18*b (there is no difference which side we take as a or b)
Now we can just solve simply equation
198=18*b /:18 both sides
198:18=b
b=11 - its the result
The answer is 11 what u have to do is 198 divided by 18. To check ur answer just multiply 18 and 11 and see if u get 198
