Honey Pie · Answer 1

1 and 5

2 and 4

3 and 3

the two widths have to be the same also the length. a square can be a rectangle not the other way around that is why 3 by 3 works

and those 3 can be flipped to make 5

Katelyn Wall · Answer 2

For a rectangle the perimeter is 2 (L+w)

where l is length

and w is width

if perimeter is 12 l and w have to equal 6 because 6 * 2 = 12

answers

(l+w)

3,3

2,4

4,2

1,5

5,1

because you can have each number represent the length and width
