Basically what u want to do is take the 36 - 12 and hopefully u should get ur answer which would be 24 inches

12 inches to 36 inches....if it is increasing (going from a smaller number to a larger number), then it is a percent increase

increase = (new number - original number) / original number...* 100
= (36 - 12) / 12.....* 100
= 24/12 * 100
= 2 * 100
= 200% increase <==

now as far as a decrease (when it goes from a larger number to a smaller number) the formula is :
decrease = (original number - new number) / original number..* 100

Area of a triangle with verticals of (-4,1),(-7,5),(0,1)

Lynna [10]

Answer:

$8 ft^2$

Step-by-step explanation:

I assume that the three points given are the vertices of the triangle. So the three points are:

A (-4,1)

B (-7,5)

C (0,1)

The area of a triangle is given by:

$A=\frac{1}{2}bh$

where b is the base and h is the height.

Here we can take as follows:

- We can take the base to be the side AC, so that its length is equal to the distance between the two points:

$AC=\sqrt{(0-(-4))^2+(1-1)^2}=4$

- The height of the triangle is therefore the perpendicular distance between AC and point B. This is equivalent the difference in the x-coordinate between any point on AC and B, so:

$h=(5-1)=4 ft$
