in finding the area if a square or rectangle multiply the length and width, for a triangle, multiply length and width divided by two.

no

The area of a triangle is expressed using the formula A=(1/2)(bh) Where A is area Where B is length of the base of the triangle. Where H is the height of the triangle. The area of a rectangle is A=BH, Where B is the length of the base of the rectangle. Where H is the height of the rectangle. Because a triangle, essentially, is a half of a rectangle, you find the area of the whole rectangle that the triangle comes from, then divide that in half.

Because a triangle is half of a rectangle. The area of a rectangle is length times width, the area of a triangle is half that.

There are several different formulae for the area of a triangle - depending on the available information - and these were invented by different people.

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.

you split your shape in half, (The rectangle and the triangle), by putting a line through it and then calculate the area of the rectangle and then calculate the area of the triangle, half the area of the triangle then add the area of the triangle and the rectangle together!Then you should have your answer!

The relationship between the area of a triangle and a rectangle is a Triangle is base times height divided by 2. Area of a rectangle is length times height.

It's half the area of a rectangle

Because a triangle is half of a rectangle. The area of a rectangle is length times width, the area of a triangle is half that.

Area of a rectangle: a = l * w

A rectangle is generally defined as a quadrilateral with four right angles. No rectangle can have four different side lengths by that definition. Finding the area of such a shape is therefore impossible.

There are several different formulae for the area of a triangle - depending on the available information - and these were invented by different people.

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.
