If the front of the birdhouse is a square with a perimeter of 40 inches, then each side will be 10 inches long.The perimeter, which is the sum of all the sides, is 40 inches. If the four sides are all equal, then each side will be 40 inches divided by 4 or 10 inches in length.
Perimeter of regular 6 sided hexagon: 6*7 = 42 inches

That is not a square, it is a rectangle and it has a perimeter of 36 inches.
Perimeter = 4*12 = 48 inches
Each side of the 48 inch perimeter is 6 inches long, therefore there are 48 / 6 = 8 of them. The figure is a regular octagon.
Each side will work out as 12/4 = 3 inches
11 sides of 4.5 inches each sums to 49.5 inches = 4 ft 1.5 inches.
