Answer:
Width=5m
Lenght= 20m
Step-by-step explanation:
L= Lenght
W= width
perimeter = (2L + 2W) ......eqn(1)
From the question, length of the rectangle is 4 times of it's width
Then
L = (4W)........eqn(2)
But perimeter = 50
Fromeqn(1)
(2L + 2W)= 50........eqn(3)
Sub eqn(1) in eqn(3)
2(4W) + 2W = 50
8W + 2W= 50
10W= 50
W=5
From (1)
L = (4W)
L= 4×5= 20
Lenght= 20
As there do not appear to be any outliers in this data set, the mean can be used to best describe the center of the data.
<h3>How to find mean and median of a data?</h3>
Mean is the ratio of sum of the observations to the total number of observations.
Median is such a number for the arranged data set(ascending or descending order) such that to its left and to its right belong same number of observations.
Ordered data values: 1, 1, 2, 2, 2, 3, 3, 5, 6, 7
Therefore, the Median = 2.5
The Mean =
![\dfrac{1+ 1+ 2+ 2+ 2+ 3+ 3+ 5+ 6+ 7}{10} \\\\= 3.2](https://tex.z-dn.net/?f=%5Cdfrac%7B1%2B%201%2B%202%2B%202%2B%202%2B%203%2B%203%2B%205%2B%206%2B%207%7D%7B10%7D%20%5C%5C%5C%5C%3D%203.2)
