Our project is over finding area and perimeter of triangles circles rectangle and trapezoid.

The circumference and area of a circle The diameter of the circle is 8in long, and the radius of the circle is half of 8in which is 4in,and the circumference 3xD = 24in.

What was our second circle measurement  our diameter for the circle was 38in.the radius was 19in.And we are going to show you some picture of how and what we measured.3x38=114in

Now we are doing triangles  Our base of our triangle was 13in,and our height was 14in. And here are some pictures of our triangle that we measured. 14 x 13 = 282 % 2=142 

Our second triangle was and our measurement……..  Here are some of our measurement we had when we were measuring. The base was 2in,and the height was 2in. Area = bh÷2  Area 2x2=4 ÷2=2in  Perimeter: add all sides 2+2+2=6
