Question 1109393
You should try this yourself.  You won't learn anything if someone else does this task for you.

Perimeter is twice the length + twice the width

P = 2L + 2W  —>  2L = P-2W  —> L=(1/2)(P-2W)

So if the first one has W=1, then  2L= 24-2(1) —> 2L = 22 —> L = 11
Your first rectangle has W=1 and L=11.

—
Set W=2,  2L = 24-2(2) = 20  —> L=10  

etc.
