Question

Consider a square and a regular hexagon (a 6-sided figure with sides of equal length). One side of the square is 4 feet longer than a side of the hexagon, and the two figures have the same perimeter. What are the lengths of the sides of each figure?

Answer 1

Notice the picture below

now, we know their perimeter are the same for both

thus 4(a+4) = 6a

solve for "a"
