Question

I'm so confused about this question for homework . Could you help me? The glee club has 120 cupcakes to sell. They have decided to arrange the cupcakes in the shape of a rectangle, such that the rows have an even number of cupcakes and the columns have an odd number of cupcakes. How many arrangements of cupcakes can they create? Explain.

Answer 1

the number of rows is the length
the nuumber of collumns is the width

alrighty
length times widdth=total number of cupcaces

so we factor 120 to find odd and even pairs
120=1*2*2*2*3*5

so some even and odd pairs are
1*120
3*40
5*24
8*15

those are all the possible pairs

so they can make 4 different arrangements
