I would guess that 4.25 pounds is another way to say 4 1/4 pounds, but without being given the answer choices, I can only give you an educated guess.
Pretty sure that you can't. It contains right angles
No problem for the answer
Answer:
Equilateral triangle (Green)
60° rhombus (2 triangles) (Blue) that can be matched with two of the green triangles
30° Narrow rhombus (Beige) with the same side-length as the green triangle
Trapezoid (half hexagon or 3 triangles) (Red) that can be matched with three of the green triangles
Regular Hexagon (6 triangles) (Yellow) that can be matched with six of the green triangles
Square (Orange) with the same side-length as the green triangle
All the angles are multiples of 30° (1/12 of a circle): 30° (1×), 60° (2×), 90° (3×), 120° (4×), and 150° (5×).
