It is not in all but a trivial sense - that they are both to do with finding the perimeter!
B+h*2 =9*-=423
Only by the definition of a perimeter.
sideways
the area of a triangle is half that of a rectangle made using two of those triangles.
Area = length x width you may try the online calculator linked below that is related to this area and perimeter calculation of common shapes like rectangle, circle, triangle, parallelogram, rhombus and trapezoid.

It's half the area of a rectangle

The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
The term "rectangle method" is used in different ways in math, but I will guess that your question is related to finding areas on a Geoboard. A Geoboard has a grid of pegs; you can make outlines of figures by stretching elastic bands around the pegs. If your figure is a triangle, you can find it's area by making the smallest rectangle which will enclose the triangle (The rectangle should have vertical and horizontal sides). The area of the rectangle can be found easily by multiplying the length by the width. The area of the triangle is half of the area of the rectangle.
if you draw a line from one corner of a rectangle to the opposite it creates two triangles
two right triangles = full rectangle That is - if you multiply height times base of a triangle, the area will be 1/2 of a rectangle having the same height, and a width the same as the triangle base.
It heavily depends on exactly how they're related.
They are characteristics of geometric shapes. However, there is no simple relationship. A rectangle with a given perimeter can have a whole range of areas.
