Answer:
the answer for the first one is 8 because we need to divide the area which is 48 by 6 to get the answer which is 8 so we multiply 6 times 8 to check if it is 48 and yes sir it is.
In the second one you need to divide 42 by 6 not by 4 and when you do that you get 7 so we multiplied 6 times 7 to check if the area is 42 and yes it is sir again so the first one is 8 and the second one is 7
