Answer: 22, 38

               3, 7

               8, 12

<u>Step-by-step explanation:</u>

It is given that the PERIMETER is BETWEEN 22 and 38

-->          22 < P < 38

Perimeter = 2w + 2L

It is given that L = w + 5

Substitute P with 2w + 2L and substitute L with w + 5

                22 <  2w + 2(w + 5) < 38

                 22 < 2w + 2w + 10 < 38    

                  12 <          4w        < 28    

-->               3 <          w          < 7          

Since L = w + 5, then w = L - 5

Substitute P with 2w + 2L and substitute w with L - 5

                22 <  2(L - 5) + 2L < 38

                 22 < 2L + 2L - 10 < 38    

                 32 <          4L        < 48    

-->               8 <            L        < 12
