They both have 2 lines of symetry
Rectangle Area of parallelogram = Base * Height Area of rectangle = Base * Height
2ab = area The sides of this rectangle are, a * sqrt(2) and b * sqrt(2) The equation of the ellipse reduces to, 0.5 + 0.5 = 1 Greetings, Dim Leed
Any rectangle whose sides are in the ratio 2:3. For example, in a 6x9 rectangle, the width (6) is two-thirds of the height (3), so it is similar to the 2x3 rectangle.

Assuming the area is a rectangle (and not an ellipse, for example), it is 15*12 = 180 square feet.
Rectangle Area of parallelogram = Base * Height Area of rectangle = Base * Height
An ELLIPSE.
An ellipse or a rectangle, depending on how you cut it.
A circle, ellipse, truncated ellipse or rectangle - depending on the inclination of the cross section relative to the cylinder.
Ellipse, Rectangle, rhombus, arrow, circle, triangle
Ellipse * * * * * At right angles to the length, it would be a circle. Along the length it would be a rectangle. Only a diagonal cross section would be an ellipse.

The answer will depend on the shape: a rectangle, an ellipse, some other shape?
Crescent. Ellipse.
A rectangle has dimensions 7 ft x 12 ft. Which of the dimensions describe a rectangle that is similar to this rectangle?
Any rectangle whose sides are in the ratio 2:3. For example, in a 6x9 rectangle, the width (6) is two-thirds of the height (3), so it is similar to the 2x3 rectangle.
They are notnecessarily the same. A circle is a subcategory of an ellipse, meaning that every single circle is guaranteed to be an ellipse, but not all ellipses will be a circle. Just like a square will be a rectangle, but not all rectangles will be squares. A circle requires that the radius remains constant throughout the entire circle, whereas an ellipse does not require this. It just has an extra requirement that disqualifies some ellipses.
