<em>Answer:</em>
<em>Width is 8 and the Length is 19.</em>
<em>Step-by-step explanation:</em>
<em>
x = width
</em>
<em>2x + 3 = length {length is 3 more than twice width} </em>
<em>Perimeter of a rectangle is 2(width) + 2(length) </em>
<em>
</em>
<em>
2x + 2(2x + 3) = 54 {perimeter = 2(width) + 2(length)}
</em>
<em>2x + 4x + 6 = 54 (used distributive property)</em>
<em>6x + 6 = 54 (combined like terms)
</em>
<em>6x = 48 (subtracted 6 from both sides)</em>
<em>x = 8 (divided both sides by 6)</em>
<em>2x + 3 = 19 (substituted 8, in for x, into 2x + 3)</em>
<em>
</em>
<em>The width = 8 and length = 19</em>
