Mathematics

Add up the lengths of the several sides of the polygon.

Examples: The perimeter of a triangle is the sum of the lengths of the 3 sides.

The perimeter of a hexagon is the sum of the lengths of the 6 sides.

And so on.

I highly recommend drawing any polygon whose perimeter you wish to calculate.

velikii [3]

Answer: $M=(7,2)$

Step-by-step explanation:

You need to use the following formula:

$M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})$

Given the points A(6,3) and B(8,1), you can identify that:

$x_A=6\\x_B=8\\y_A=3\\y_B=1$

Now, you can substitute these values into the formula $M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})$ .

Therefore, you get this result:

$M=(\frac{6+8}{2},\frac{3+1}{2})$

$M=(7,2)$
