Answer:
28 feet
Explanation:
Since each side length of the square is 1 foot.
Let x represent the length of the small slant side and y represent the length of the long slant side. Hence:
x² = 5² + 1²
x² = 26
x = √26 = 5.1 feet
y² = 6² + 3²
y² = 45
y = 6.7 feet
The perimeter of the figure is the sum of all the sides of the figure, hence:
Perimeter = 11 feet + 4 feet + 5.1 feet + 6.7 feet + 2 feet = 28.8 feet
Therefore the best estimate of the perimeter of the figure below is 28 feet.
