Question 1132343
.
<pre>
If x is the width, then the length is (2x+8).


The perimeter is


    x + (2x+8) + x + (2x+8) = 76 centimeters,  or


    6x + 16 = 76


    6x = 76 - 16 = 60


    x = {{{60/6}}} = 10 centimeters is the width.      <U>ANSWER</U>


    Length = 2*10+8 = 28 centimeters.          <U>ANSWER</U>


<U>CHECK</U>.   The perimeter is  10 + 28 + 10 + 28 = 20 + 56 = 76 centimeters.   ! Correct !
