Only three sides is one possible answer.
A rectangle has four sides and four angles. A rectangle is a closed shape. All four angles of a rectangle are right angles. That is, they are 90 degrees. Opposite sides of a rectangle are the same length. Opposite sides of a rectangle are parallel. That is, if they were extended infinitely they wouldn't touch. ***Additionally, the diagonals of a rectangle are congruent (unlike other parallelograms), and they also bisect each other. While all parallelograms share the bisecting diagonals characteristic, only rectangles (and by extension squares) have congruent diagonals.***
Rectangle area = (rectangle width) x (rectangle height)
A = lw Area of a rectangle = length times width
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
Rectangle
A rectangle is a quadrilateral. As such, it shares the distinguishing characteristic of quadrilaterals with all other quadrilaterals, and has four (4) sides.
The answer depends on the what characteristic of the pyramid you want the formula for: its surface area, its volume or something else.

No, two equilateral triangles do not form a rectangle when placed together. While you can arrange two equilateral triangles in various ways, such as aligning their bases or placing them vertex-to-vertex, the resulting shape will not have the right angles or equal opposite sides characteristic of a rectangle. Instead, their arrangement will typically create a different polygon or a shape with angles that do not conform to the requirements of a rectangle.
crossed rectangle is not a rectangle, rectangle have to have 90 degree angles.
A rectangle, a pentagon, and an arrow all share the characteristic of being geometric shapes. They can be defined by their vertices and edges, with the rectangle having four sides, the pentagon having five, and the arrow typically represented as a combination of triangular and rectangular shapes. Additionally, all three can be used in various design and artistic contexts to convey direction, structure, or form.

Every rectangle must have corners otherwise it would not be a rectangle!Every rectangle must have corners otherwise it would not be a rectangle!Every rectangle must have corners otherwise it would not be a rectangle!Every rectangle must have corners otherwise it would not be a rectangle!
Because a rectangle has two pair of parallel line and it is a rectangle.
a rectangle cant be a square but a square can be a rectangle
Rectangle is spelled correctly.
