*Lets do some example problems here, so we have the perimeter of each of the outer triangles is 30.So for example if I took The sum of this side, this side, and that side I will get 30 and that is true of all these outer triangles, these 5 outer triangles.The area of a square A = s = 9 If formulas for a figure do not exist, we can still find the perimeter by adding the lengths of the sides. We calculate the perimeter by adding the lengths of the sides. The line extends 8 units to the left and 7 units to the right. If a formula exists, use it to find the perimeter and the area.*

All we need is to get the perimeter of all triangles, subtracted out these bases which was the perimeter of the inner pentagon and we are done. What is the area of this this quadrilateral, something that has 4 sides of ABCD?

And this is a little bit we have not seen a figure quite like this just yet, it on the right hand side looks like a rectangle, and on the left hand side looks like a triangle and this is actually trapezoid, but we can actually as you could imagine the way we figure out the area of several triangles splitting it up into pieces we can recognise.

Just call them 5 triangles like this minus their basis, right, if i take the perimeter of all of these sides If i added up the part that should not be part of the perimeter of the star would be this part,that part, that part,that part, that part and that part.

those are not the part, those are not the part of the perimeter of the star so should be the perimeter of the 5 triangles minus the links of their bases links of their 5 bases. well, the perimeter of each of them is 30, perimeter of 5 of them is going to be 5 times 30 which is 150, now we want to subtract out the links of their 5 bases now the links of their 5 bases if we add them up is the exact perimeter of this in inner pentagon right over here.

So it is this side, let me do this in a new color actually So the perimeter of the triangle i will do in orange.

It is going to be this plus that plus that plus that plus that plus that i think you get the idea plus that plus that plus that plus that So the perimeter of the of the star so let me call this: perimeter perimeter of the star it is going to be equal to the perimeter of the 5 triangles is equal to perimeter of 5 outer triangles.Thus, (3,0) is the point located at x = 3 and y = 0. If a formula exists, use it to find the perimeter and the area.Plotting the coordinates gives a picture of the figure. The perimeter can be calculated as P = 4s where s is the length of the side of the square.And the most obvious thing to do here is started A and just drop a rock drop an altitude right over here, and so this line right over here is going to hit at 90 degrees and we could call this point E.And what is interesting here is we can split this up into something we recognize a rectangle and a right triangle.But you might say how do, how do we figure out what these you know we have this side and that side, so we can figure out the area of this rectangle pretty straight forwardly.But how would we, how would we figure out the area of this triangle?Anyone can earn credit-by-exam regardless of age or education level.
