Answer:
Step-by-step explanation:
In this problem, the amount of wood refers to the length of the frame, modeling it as a long piece of wood.
Thus, the amount of wood is equal to the perimeter of a rectangle with dimensions width = 8 inches, and length = 3×8 inches = 24 inches.
The perimeter of a rectangles is 2 × width + 2 × length:
- 2 × 8 inches + 2 × 24 inches = 16 inches + 48 inches = 64 inches.
