So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.
WebbQuadrilateral. A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees. The word quadrilateral is derived from the Latin words ‘Quadra’ which means four and ... WebbPerimeter = 2 × length + width. Example 2: Work out the perimeter of the following polygon: Perimeter = Sum of the length of all the sides. = 13 cm + 3.5 cm + 3.5 cm + 13 cm + 4 cm = 37 cm. Example 5: Area of a square is given as 100 cm 2. Find its perimeter. Area of square = 100 cm 2. Formula for area of square = Side x Side.
