JORDYN AND JAIME PERIMETER AND AREA.

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

Now we are doing our rectangles

This is our first rectangle that we measured. The formula is l x which is area. The length of our rectangle was 11in,and the width is 2in,and the area is 22in2. and here are some pictures of how and what we measured.

This is our second rectangles

Our length of our rectangle is 4in,and the width is 2in.4 x 2=8 and that’s the area of the rectangle , and here are some pic.

trapezoids

Here is the formula for the trapezoid. B1 + b2 x h ÷2 = area. and the area was is 1,524 in 2. and here are some pic.
