Answer:
let length be x and breadth be y
by question
L=4×1/2×B
L = 2B
now
Area of rectangle=L×B
2B ×B
2B^2
Is it correct? ,I actually tried to solve it
Answer:
43.8 is the Area but i don't know about the perimeter
Step-by-step explanation:
When the number of data points is odd the formula to find the Ranking of the Median is (n+1)/2, When the number of data points is even the ranking of the Median will be the AVERAGE of n/2 + n/2 +1, where n is the number of data points.
In our case the ranking of the Median is the average (20+21)/2 = 20.5.
1- How many points are below the Median =20
Lower half = 20, Upper half = 20 & Median = 20.5 (Don't forget Median is the ranking of data points).
Again the 1st Quartile is at 10.5, so 10 data points are below the 1st Quartile
and 20 points are between Q1 & Q3
I believe the answer is 60
