If you're trying to get b by itself, divide 14b by 14, so that b is left alone, since the opposite of multiplying 14 by b, is dividing 14 by b to get b alone. So now, b = 42 divided by 14, which is 3. Tell me if it doesn't make sense, hope this helps!
Im not sure if you need to find the area or de expression of how to find the AREA. but what you do if explain how you can find it by multiplying that will be 4.. and then also 4? Im not sure but you can try
