The area of the garden is the amount of space on the garden.
- The area of the total garden is (x + 15)(x + 20)
- The width of the pathway is 1 meter
The dimensions of the garden is given as:
15 meters by 20 meters
Let the width of the pedestrian pathway be x.
So, the area of the total garden is:
In (a), we have:
The total area is given as: 336.
So, we have:

Evaluate
Expand
Factorize
Factor out x + 36
Solve for x
x = -36 or x =1
The width cannot be negative.
Hence, the width of the pathway is 1 meter

Answer:
IQR = 6
Step-by-step explanation:
Given:
The given set of data is:
40 41 42 43 44 45 46 47 48 49 50
Number of terms,
Therefore, the median is given as term which is the sixth term. Median = 45
(40 41 42 43 44) <u>45</u> (46 47 48 49 50 )
Now, we find the median of the lower half () and upper half (
)of the data that are before and after the median.
The lower half of the data has the values 40 41 <u>42</u> 43 44.
Number of terms are 5. So, median is the third term which is,
The upper half of the data has the values 46 47 <u>48</u> 49 50.
Number of terms are 5. So, median is the third term which is,
Now, IQR is given as the difference of upper half median and lower half median.
