### Area of Square of side 85 - and Geometric properties like symmetry,perimeter,diagonal,inradius,circumradius

 Area of a square with side 85 units = side * side = 85 * 85 = 7225 square units Perimeter of a square with side 85 units = 4 * side = 4 * 85 = 340 units Diagonal of a square with side 85 units = 21/2 * side = 1.414 * 85 = 120.19 units Inradius (radius of incircle) of a square with side 85 units = side/2 = 0.5 * 85 = 42.5 units Circumradius (radius of circumcircle) of a square with side 85 units = side/21/2 * = 85/1.414= 60.11 units Area of incircle of a square with side 85 units = PI * side2/4 = 3.14 * 0.25 * 85 * 85 = 5671.63 square units Area of circumcircle of a square with side 85 units = PI * side2/2 = PI * 85*85/2= 11343.25 square units Order of symmetry of a square is 4 (number of times the shape co-incides with itself during a 360 degree rotation) Number of axes of symmetry of a square is 4 - two diagonals and the other two lines cross horizontally and vertically through the middle of the square. To understand more about the geometric features and properties of squares, formulas related to mensuration etc. you might find it useful to read the properties of a Square tutorial over here. Many of these concepts are a part of the Grade 9 and 10 Mathematics syllabus of the UK GCSE curriculum, Common Core Standards in the US, ICSE/CBSE syllabus in India.
