Answer: 400 inches by 10 inches
Step-by-step explanation:
Length of the bridge = 4000feet
Width of the bridge = 100 feet
Since Sue decides that her scale model needs to be 1/10th the size of the real bridge.
If she uses a scale of inches to feet, the dimensions of her model will be:
Length = 4000 × 1/10 = 400 inches
Width = 100 × 1/10 = 10 inches.
Therefore, the dimensions are 400 inches by 10 inches
