Answer:
The slope of the green line is 3.
Step-by-step explanation:
<em><u>Definition: </u></em>If the two lines are said to be perpendicular, than the multiplication of their slope is -1.
In other words, the slope of the perpendicular line is the negative reciprocal of the given slope of the line.
Here we are slope of the red line, which is -1/3
Let's take it as "m1"
Let's take "m2" the slope of the green line.
By the above definition,
Given:
Now plug m1 value in the above statement, we get
Multiply both sides by reciprocal of -1/3. The reciprocal of -1/3 = -3
Therefore, the slope of the green line is 3.
To find the area of a rectangle, you use this equation/formula:
A = l x w
Since you know the area and the length, you can plug it into the equation:
A = l x w [A = 96 in² l = 8 in]
96 = 8 x w
To find the width, you divide 8 on both sides
12 = w
The width is 12 inches
To find the perimeter of a rectangle, you add all of the sides together:
P = l + l + w + w or P = 2l + 2w
Since you know the length and width, you can plug it in:
P = 2l + 2w
P = 2(8) + 2(12)
P = 16 + 24
P = 40 in
.32 because you have to take away the ones place for an accurate answer!
