Area of a triangle = 0.5*base*perpendicular height
Area of a parallelogram = base*perpendicular height
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
If the heights and bases are the same, then the triangle is half the area of the parallelogram.
If the heights and bases are the same, then the triangle is half the area of the parallelogram.
It is base x height for the parallelogram. That is twice the area of a triangle which is: 1/2 base x height. (Base and height being the same for both cases).
They both use perpendicular height and are in square units. Area of a trapezoid = 0.5*(sum of parallel sides)*perpendicular height Area of a parallelogram = base*perpendicular height
The parallelogram has twice the area of the triangle if their bases are the same and their heights are the same. Area triangle = 1/2 base x height. Area parallelogram = base x height.
I don't know about the relation in the perimeters of a triangle and a parallelogram but if a triangle is on the same base on which the parallelogram is and the triangle is between the same parallel lines of the parallelogram, then the area of the triangle will be half the area of the parallelogram. That is, area of a triangle = 1/2 area of a parallelogram if the triangle is on the same base and between the same parallel lines.
you do it because the triangle is half the size of the parallelogram
They involve only the base and vertical height.The formula for a triangle is half that for the corresponding parallelogram.
Do you know the formula for the area of a triangle ? Pick a base-length and a height for your triangle so that 1/2 (base x height) = 20. Do you know the formula for the area of a parallelogram ? Pick a base-length and a height for your parallelogram so that (base x height) = 20. We're having a problem understanding your difficulty. Of course, if you don't know the formulas for area . . .
To get the area it half breadth by height. A simplified thought on this is because the formula for the area of a parallelogram is length by width, and a triangle would be half of this
The formula for area of a parallelogram is bh. Base times height.
