All you have to do is plug numbers into the equation perimeter = (length x 2) + (width x 2)…

So for perimeter 42, you can have:

length 1 width 20

length 2 width 19

length 3 width 18

length 4 width 17

length 5 width 16

length 6 width 15

length 7 width 14

length 8 width 13

length 9 width 12

length 10 width 11

and for perimeter of 32, you can have

length 1 width 15

length 2 width 14

length 3 width 13

length 4 width 12

length 5 width 11

length 6 width 10

length 7 width 9

length 8 width 8

(you can switch the length and width around, it’s not important which is which)

Hope that helps!
