b) The actual width of the park is 6 yards.
c) The actual length of the park is 520 inches.
d) The scale factor is 1:80

Answer 1

The scale factor is 1 : 2340 . And the Actual width of the park is 390 yards

Using the standard conversion

Comparing the actual and drawing length ;

• drawing length : Actual length

We have ;

Scale factor = 8 : 18720 = 1 : 2340

The actual width of the park ;

• 6 × 2340 = 14040 inches

Width in yards ;

14040 / 36 = 390 inches
