Answer:
40 feet by 4 feet
Step-by-step explanation:
Given length (l) = 100 feet
width (w) = 10 feet
As mentioned in the question the size of garden is decreased to 2/5 of its size. <u>It will effect the length and width with the same proportion.</u>
So,
New length = 100 * 2/5 = 40 feet
New width  = 10 * 2/5 = 4 feet
Therefore, the scale of new drawing would be 40 feet by 4 feet

Here is an example:
 Find the MAD of 2,4,6,8 Step 1 : Find the mean of the data : (2+4+6+8) / 4 = 20/5 = 4 Step 2 : Find the distance between each data and mean. Distance between 2 and 5 is 3 Distance between 4 and 5 is 1 Distance between 6 and 5 is 1 Distance between 8 and 5 is 3
Step 3 : Add all the distances : 3+1+1+3 = 8 
Step 4 : Divide it by the number of data : 8 / 4 = 2 2 is the average absolute deviation.
