So yesterday was my birthday December 28 and my parents gave me a wall mountable lamp. And my grandparents gave me new 3D printer. The box was massive and really heavy, after I opened it I was very Happy and surprised. My printer was called MP Inventor 1. My first project was a super cool looking cube. The image of it will be on the side. And so far a really enjoy the printer.
Today I am going to tell you how to find the area of a shape with a hole. To find the area, first we need to find the area of the shape in the middle, or the hole. Next, we need to find the area of the shape with the hole in it. So, like in my other post , where I taught you how to find area and perimeter, we multiply the sides again, and get our area. We find the area of the hole. And then we subtract the area of the hole from the area of the big shape. For example, if the big shape area sides are 8 and 10, then its area will be 80. The same thing with the hole, if one side is 4 and the other side is also 4, then we multiply them and get 16. Then we subtract 80-16 and we get our area, 64.
Really I enjoy your site with effective and useful information. It is included very nice post with a lot of our resources.thanks for share. i enjoy this post. 3d lampe
