Question

how do you find a area of a triangle for a 6 th graders? area of a circle?

Answer 1

if you look at the triangle, it should be drawn with one line flat that goes in the same direction as the bottom of your paper. This line is your base. From the top point of the triangle to that line, there is a straight line whose length is the height of the triangle. If there is a 90 degree angle next to the base, then that line is your height, but not all triangles are like that. If you multiply (1/2) x (the length of the base) x (the height), This is the area of the triangle. For the circle, There is a length from the center of the circle to the circle, that is called its radius. There is another number called pi that is roughly equaly to 3.14, that is used to calculate the area. (I would tell you what the number comes from, but I don't want to confuse you with it just yet. ) The area of the circle is that number pi = 3.14 x (the radius of the circle squared). When we say the number is squared, what we are saying is that the number is multiplied by itself one time, so literally it is Pi x Radius *radius. This is your cirlce area.
