Question

A triangle with vertices located at (−2, −2) and (4, −2) has an area of 24 square units. Which is one possible location of the other vertex?

Answer 1

Answer:

Actually, the answer is (4, 6).

Step-by-step explanation:

I did this problem on a test and got it correct. Also, I know that the formula for a triangles area is bh/2 or base*height divided by 2.The absolute value of the x-values combined is the base which is 6 because I -2 + 4 I = 6 units. To find a height that would give you 24 units squared, you would have to multiply the height that you would put for a rectangle ( 4) by 2 which is 8 units. If you add the absolute value of the y-value in the points ( -2, -2) or ( 4, -2) to the absolute value of the y- value in (4, 6) which gives you the equation I -2 + 6 I = 8 units It will prove that (4, 6) is the missing vertices for the right triangle.

Hope this helps.......Your welcome!!!

Answer 2

To find the other possible location, you can find the distance between the two ordered pairs that are given.

From (-2, -2) (4, -2), there is a distance of 6 units. We can see this with the X values. From -2 to 4 on a number line is 6 units.

To create a triangle with 24 square units, you will need to think of creating a space that is 48 square units if it were the shape of a rectangle.

6×8 = 48, and half of that, the area of the triangle, would be 24 square units.

Eight units on the Y axis from (-2, -2), would be (-2, 6).

One possible location is (-2, 6).
