Solution

The correct option is B 1360
Given:
Length in the model = 10 inches
Actual length = 100 yards

1 yard = 36 inches
Actual length =100×36=3600 inches

We know that,

Scale factor

= Dimension of scale model Dimension of actual object

= 10 inches 3600 inches

= 1360

Hence, option (b.) is correct.
