Width of the table is 66 inches.
<u>Step-by-step explanation:</u>
Perimeter of rectangle is twice of width and length,
i.e. P = 2( l + w )
According to question, length is 26 inches longer than width
∴ l = w + 26
Now,
<em>P = 2( l + w ) = 316 inches</em>
<em>⇒ 316 = 2( l + w ) </em>
<em>⇒ 316 = 2( w + 26 + w ) </em><em> </em>∵ l = w + 26
<em>⇒ 316 = 4 w + 52</em>
<em>⇒ 264 = 4 w</em>
<em>⇒ w = </em><em>66 inches</em>
