The area of the land is , because it's a square with side 250.
The path forms an inner square whose side are 20 feet less, so the area inside the path is
So, the area of the path is the difference between the outer and inner square:
Answer:
70
Step-by-step explanation:
To find the quartiles of a data-set, we must first split the data through the middle.
This puts 50, 70, and 90 on the left.
And 110, 30, and 150 to the right.
The quartiles would be the median of these (3) numbers.
Since we are finding the Lower Quartile, we find the median of
50,70 and 90.
It will be 70.
In this problem, the reference of the scale is referring to feet. Firstly, convert 72 inches to feet so that you can properly make the proportion.
72 inches = 6 feet
With the scale of 2 inches per 3 feet, we can set up an easy proportion to see how wide the door will be on the drawing.
3 feet 6 feet
——— = ————
2 inc. ‘x’ inc.
3x=12
X=4 inches
Solving the proportion by cross-multiplication reveals that the scale drawing of the patio door would be 4 inches wide.
