How to calculate the P: the p of this shape is pretty much easy to solve. Finding a P of a shape, you need to add all the sides up. So you just need to add 9+6+2+5+5+5+2+6. Remeber to double check that you got all the sides. Anothor equation you can do is (6x2) + (5x3)+(2x2)+9. Just pick a equation to do and you get the answer
how to caculate the A: Caucalating the A of this shape is actually a little hard. There is two ways to solve this but the second way to me is kinda hard. The first way is two divide this shape into rectangles and squares. So I dived it like this ( look at the image below). To calculate the area of a rectangle is to mutiply lengh by width. So first I will need to multiply 9x6 to find the first area of the rectangle. Then I have to multiple 5x5 to find the area of the second square. Then I just have to add the answer of the first answer to the second answer is 54+25.
Move b a bit further if the angle between cd and ab changes when you move b if you want to make a perpendicular point to cd The angle BEC is 90 ° for making the AB line perpendicular to the line CD to transfer point B to the angle between the two lines.
It is not a circle but you can find the equation of the ellipse. To do this we need to work out the major and minor radii and the centre The centre is at (9, 7) The major (y) radius is 1 and the minor (x) radius is 5 Therefore the equation is (x-9)/5 + (y-7)/1 = 1
