Answer:
The width is 7 inches and the length is 9 inches
Step-by-step explanation:
So we can divide 32 by 2 because we know perimeter is 2(l*w)
So it becomes 16, and it is now (l*w)
We know that the length is 2 inches longer so we subtract 2 from 16.
It then becomes 14 inches so therefore we can then divide it by 2.
14 divided by 2 is 7 and therefore we add 2 because we subtracted the two from earlier temporarily.
Therefore the width is 7 and the length is 9.
