Answer:
<u>27</u> students are girls.
Step-by-step explanation:
Given:
There are 3/4 as many girls as there are boys.
In the fifth grade total there are 63 students.
Now, to find the number of students that are girls.
Let the number of students that are boys be
So, the number of students that are girls =
Total number of students = 63.
Now, to get the number of students that are girls we solve an equation:
Now, substituting the value of :
Therefore, 27 students are girls.
To find the perimeter of a rectangle, we can use this formula: 
Where L is the length and W is the width.
We know the perimeter and we know the length and we want to find the width.
Substitute the values back into the formula.
2(35) + 2W = 84
70 + 2W = 84
2W = 14 <-- Subtract both sides by 70
W = 7 <-- Divide both sides by 2
So, width is 7 meters long.
Where L is the length and W is the width.
We know the perimeter and we know the length and we want to find the width.
Substitute the values back into the formula.
2(35) + 2W = 84
70 + 2W = 84
2W = 14 <-- Subtract both sides by 70
W = 7 <-- Divide both sides by 2
So, width is 7 meters long.
