The dimensions of the original drawing of park is 4 feet.
A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.
Given:
Scale of Park: 5 inches : 2 feet
Now, Area of Park scale Drawing = 100 sq inches.
side² = 100
side= 10 inches.
As, 5 inches= 2 feet
1 inches= 2/5 feet
So, 10 inches= 10 x 2/5 = 4 feet
Hence, the original dimension is 4 feet.
