Question

Harry had a pile of 48 pennies . He organized them into a rectangular array. It had exactly four rows with 12 pennies in each row. Draw diagrams to represent at least two other rectangular arrays Harry could use. Do you think there are more

Answer 1

Number of Pennies Harry has=48 pennies

Array is an arrangement of some object which we represent through number in the form of rows and columns.

`P_(ab)`

a=Number of Rows

b=Number of Columns

48 can be written as

`1.\rightarrow 48_(4 * 12)\\\\2.\rightarrow 48_(6 * 8)\\\\3.\rightarrow 48_(8 * 6)\\\\4.\rightarrow 48_(12 * 4)`
