Answer:
The border will be 18.6 inches wide
Step-by-step explanation:
<em>Let the width be w</em>
<em>The length = 43 inches</em>
<em>Total wood = 800 square inches</em>
Formula for area of rectangle = length x width
<em>800 = 43 x w</em>
<em>w = 800/43</em>
w = 18.6 inches
Therefore, the border will be 18.6 inches wide.
