Abuilding is 200 feet long and 140 feet wide oh 1/500 model is built on the building how long and how wide is the model

The length would be 4.8 inches or 0.4 ft and the width would be 3.36 inches or 0.28 ft.

This is found by multiplying the length and the width by the scale factor, 1/500:

200*1/500 = 200/500 = 2/5 =0.4 ft.  Multiplying this by 12 for inches, 0.4(12) = 4.8 inches.

140*1/500 = 140/500 = 7/25 = 0.28 ft.  Multiplying this by 12 for inches, 0.28(12) = 3.36 inches.
