Let w = width of the rectangle 
<span>4w+7 = length of the rectangle </span>

<span>perimeter = 2 lengths + 2 widths </span>

<span>2w + 2(4w+7) = 54 </span>
<span>2w + 8w + 14 = 54 </span>
<span>10w = 40 </span>
<span>w = 4 </span>
<span>4w+7 = 23 </span>

<span>dimensions of rectangle: </span>
<span>width = 4 </span>
<span>length = 23 hope this helps</span>
