It is possible for a square to be a rectangle, but it is impossible for a rectangle to be a square. In order to be a square, the shape must contain four straight sides with 90-degree angles that are all the same length.
Know MoreA rectangle has four straight sides with four right angles, but the sides can be different lengths. The opposite sides of a rectangle must be parallel with one another and feature equal lengths. This means the shape can be tall and skinny or short and fat. The sides on a square must all be parallel in comparison with one another.
Learn more about GeometryTo calculate the area of a rectangle, multiply the length of the rectangle by its width. You need to know the length and width of the rectangle. A ruler, a pen, a paper and a divider are helpful in completing this task.
Full Answer >A rectangle is a simple shape that is characterized by having four sides at 90-degree angles to each other, and having both sets of opposing sides be the same length. Note that if all sides are equal to each other, the shape is not a rectangle, but a square.
