I'm sure there are easier ways to do this but the "brute force" method is to label point A as x1, y1; point b as x2, y2 and point c as x3,y3. Then just do square root of the sum of: (x2-x1)squared+(y2-y1)squared. Save this into memory 'A'. Now do the same for x2,y2 to x3,y3 and add this to the number saved in 'A' and do it once more for x3, y3 to x1, y1 and add to the number in 'A' to get the result.

If all sides are equal then 2x + 5 = 4x - 3

2x = 8

x = 4

so the perimeter is 3 times either expression above

3 * (8 + 5) = 39

.

2x = 8

x = 4

so the perimeter is 3 times either expression above

3 * (8 + 5) = 39

From the three points you give, the perimeter appears to be the three sides of a triangle going from (9, 7) to (8, -3) to (2, -6) and back to (9, 7).

Or are you actually asking for something else? The length, perhaps? That would be about 31.5 .

Since you have
the coordinates of the three vertices, the most straightforward method
is to calculate the length of the sides using the distance formula

d(P_1,P_2)=SQRT(**(X_1-X_2)^2**+(**Y_1-Y_2)^2**)

where SQRT is the**square root function**, X_1, Y_1) are the coordinates of point P_1, etc.

With the three lengths available, use Heron's (sometimes called Hero's) to find the area.

**Here is Heron's formula.**

Let's call the lengths**a, b, **and** c**

Let p be the semi-perimeter p= (a+b+c)/2

Then

Area= SQRT [**p(p-a)(p-b)(p-c)** ]

Make sure that there is a matching ) parenthesis to the one in the SQRT.

Alternatively,

You can choose the base as the side opposite the vertex (0,0)

Calculate the equation of the line that supports the base.

Calculate the equation of the line issuing from (0,0) and perpendicular t the base.

Calculate the coordinates of the intersection point , call it H, of the base and its perpendicular line (coming from (0,0)).

Calculate the distance OH, that is the height relative to the chosen base.

Use the formula**Area= base*height/2**

Now it is up to you to choose one of the two methods and calculate the area of that triangle. The second method involves more calculations than the first, and more possibilities of errors. Good Luck

The perimeter of any triangle is the sum of the lengths of the three sides. Are you asking about a specific triangle? "On a grid" doesn't describe a triangle very well.

Here is a list of shuffleboard penalties:

1. When players slides their own puck beyond the scoring triangle
and into the "10 off" zone, 10 points are deducted from that player's
total.

2. If a puck is knocked into the "10 off" zone by another
player, the player whose puck was knocked into that zone will be deducted 10
points.

3. If a player's puck is touching the line of the "10
off" area on the shooting side before their puck is played, they will be
deducted 5 points.

4. For any shot that lands on the sideline or off the side of the
board will be deducted 10 points.

5. If any part of a player's body crosses the baseline while
shooting a puck, that player is deducted 10 points.

6. If a player accidentally shoots another player's puck, they are
deducted 10 points.

Let ABC be the equilateral triangle,

and PC be the line joining the mid point of A and C.

We know that equilateral triangle has equal angles which means

Now,

in triangle AHC

Sin(THETA) = AH/AC

That is...

Sin(60) = (7root3)/AC

or AC = (7root3)/Sin(60)

AC=14

Perimeter of equilateral triangle ABC = 3 x Side

= 3 x 14

= 42

and PC be the line joining the mid point of A and C.

Hi nanaeden

Use the formula depending on what is given

If one side and vertical height from that side to the opposite vertex is given, use the formula 1/2 of basexheight

If 3 sides of the triangle are given use the formula

sq root of [ s(s-a)(s-b)(s-c)] where a,b, c are the 3 sides and s is semi- perimeter.

Familiarise with formulae to solve Maths problems.

If it is helpful, please give a rating.

Have a nice day
