Question 1191335
.
<pre>

Half the perimeter is 24/2 = 12 inches.


So, the sum of the length and the width is 12 inches and the difference is 4 inches.


Hence, the length is  half the sum of 12 and 4  

    length = {{{(12+4)/2}}} = 8 inches.


And the width is half the difference of 12 and 4  

    width = {{{(12-4)/2}}} = 4 inches.

Solved.
