The breadth of rectangle is 14 cm
The perimeter of rectangle is 65 cm
<em><u>Solution:</u></em>
Given that,
Area of rectangle = 259 square centimeter
Length of rectangle = 18.5 cm
<em><u>The area of rectangle is given by formula:</u></em>
Substitute the given values in above formula:
Thus breadth is 14 cm
<h3><u>Find the perimeter:</u></h3>The perimeter of rectangle is given by formula:
Substitute the given values in above formula:
Thus perimeter of rectangle is 65 cm
This question is incomplete.
The complete question says;
The two-way table shows the number of hours students studied and whether they studied independently or with a study group.
What is the relative frequency of students that studied independently for more than 2 hours to the total number of students that studied independently?
a) 0.4 c) 0.25
b) 0.33 d) 0.11
Table is attached as image
Answer: C (0.25)
The number of students that studied for more than 2 hours as given in the table are 4.
The total number of people that studied independently include those that studied less than 2 hours and those that studied for more than 2 hours.
Those that studied less than 2 hours independently are 12.
Those that studied more than 2 hours independently are 4.
Hence the total number of people that studied independently is 16.
Therefore the relative frequency of students that studied independently for more than 2 hours to the total number of students that studied independently would be = 4/16 = 1/4 = 0.25.
