Question 1100955
<br>
The square has 4 sides, each of which is 3 feet longer than each of the 6 sides of the regular hexagon; and the perimeters of the two figures are equal.<br>
So if x is the length of a side of the hexagon,
{{{4(x+3) = 6(x)}}}
{{{4x+12 = 6x}}}
{{{12 = 2x}}}
{{{x = 6}}}<br>
The side of the hexagon is x=6; so the side of the square is x+3 = 9.
