Draw a rectangle with sides 6 cm and 3 cm, calculate its area with a segment

Draw a rectangle with sides 6 cm and 3 cm, calculate its area with a segment, divide the rectangle into 2 equal triangles and calculate the area of each of them.

First you need to calculate the area of the rectangle. As we know, for this it is necessary to multiply the length and width of the rectangle among themselves. Let’s find its area:

6 * 3 = 18 cm ^ 2.

So, we divided the rectangle into 2 equal triangles, that is, the area of the rectangle was divided into the area of two identical triangles. The sum of the areas of these two triangles is equal to the area of the rectangle. Let’s write it down with the equation. x is the area of the triangle:

x + x = 18.

2x = 18.

x = 18: 2 = 9 cm ^ 2.
