Find the perimeter of the triangle whose vertices are the following, specified points in the plane. (-10,-3), (1,4) and (-1,7)

Given:

The vertices of the triangle are (-10,-3), (1,4) and (-1,7).

To find:

The perimeter of the triangle.

Solution:

Distance formula:

Let the vertices of the triangle are A(-10,-3), B(1,4) and C(-1,7).

Using distance formula, we get

Similarly,

Now, the perimeter of the triangle is

Therefore, the perimeter of the triangle is 30.098 units.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

what i would say the best answer is a. 40.5
