Not sure this is correct

l=16 w=3

16×3 =48

factors of 48 are 1, 2, 3, 4, 6, 8, 12,16, 24, 48

lxw =48, and options are 1×48, 2×24, 4×12, 6×8, 16×3

16+3=19 which is a prime number, the rest do not add up to give a prime number. Again I am not sure this is correct.

2)a)10, b)6, c)24, d)12, e)40, f)30,g)60, h)24, i)45 j) 30

I have only listed the LCM, you need to list the multiples

It has been a long time since I solved these type of problems, so may not be correct

Please pay attention in class, these are easy problems once you understand them.

i dont think the first is possible…no matter what the length and width are, if you add them you should get 24.

Now, you can have a prime number for the sides.

L=13, W=11.

2(13+11)=48
