A rectangle and a parallelogram have the same formula for area:
The area of a parallelogram is given:
area = length × width
where:
In the formula for the area of a rectangle, the width (perpendicular distance between the sides given for the length) is also the length of the other two sides.
rectangle
because they are the same shape
Add up the lengths of all the sides. (Same for any shape [except a circle])
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).
The area of a rectangle is Base x Height and its the same thing as a parallelogram but the area of a triangle is Base x Height divided by 2 So unless its a parallelogram you just X all the sides.
rectangle
The formula for the area of a parallelogram is heightxbasethe reason that that is the formula is because it has th same height on both sides and the base stays the same even if it was on a unique angle and that's how you get the area of a parallelogram.The area of a parallelogram is base time 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.
That they could be congruent if they have the same interior angles
because they are the same shape
Add up the lengths of all the sides. (Same for any shape [except a circle])
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).
a parallelogram that has the same shape but not the same size called "similar". This means the angles are equal in both shapes but the sides are different.
The area of a rectangle is Base x Height and its the same thing as a parallelogram but the area of a triangle is Base x Height divided by 2 So unless its a parallelogram you just X all the sides.
of course base times height for a square or rectangle. but for a trapezoid a= h x "b1+b2"
The formula for the area of a parallelogram is the same as for a rectangle. base x height Just remember that the height is a line drawn perpendicular to the base, not the other side length.
No. You can push a cylinder across its axis - in the same way that a rectangle can be made into a parallelogram. The new cylinder would have a different shape.
