Oblongs are rectangular shapes that have a longer side than the other. Some other synonyms for oblongs include rectangles, elongated rectangles, oblong-shaped figures, and elongated figures. These terms refer to geometric shapes that have four straight edges and four angles, with two pairs of opposite sides that are equal in length. Other possible synonyms for oblongs are rectangular prisms, which are three-dimensional shapes with a rectangular base and sides that are perpendicular to the base, and parallelepipeds, which are three-dimensional shapes with six faces that are all parallelograms. These terms are often used in mathematics, architecture, engineering, and other fields that involve measurements and geometry.
