Well...regions on a geoboard is basically just a geoboard split into a certain amount of sections. Say you had a geoboard with a band stretched diagonally across with one segment (line) it would be 2 regions. If you had 3 segments (lines) the maximum number of regions would be seven. Geoboards are really fun but i personally like regions the best. A challenge is to find all the maximum number of regions from 1-9..its actually really hard and no number 4 is snot 10 it is 11!! Good Luck!
no triangles
Rectangle is length times width and triangles are base times height divided by 2.
It can be divided into 5 equal triangles so find the area of a triangle and then times it by 5. Area of a triangle is 0.5 times base times perpendicular height.
Find the areas of the rectangles and triangles. Add them together.
Trigonometry is used to find the properties of triangles and Pythagoras' theorem is used to find the lengths and angles of right angle triangles.

find the formula for that shape, which is made of 2 triangles, so if you find the base and height of each of those triangles, find the area of each and add them together, i think you should get the proper area
1 method is to multiply length times the width and the 2 method is to divide the rectangle into triangles and find the area of one of the triangles and multiply the area by two.
Find out the number of matchsticks that the learners would need to build 40 triangles
It depends on what type of shape you are trying to find the area. If it is a rectangle, you do base times height. For triangles, you do base times height divided by two. For a circle, it is Pi*R^2.
Triangles you use : (base x perpendicular height) divided by 2. Parallelogram: you need to find the area of one of the side triangles, then double it (because there's two of them). Then find the area of the square in the middle, and add this to the area of the two triangles.
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.
