A square is a regular polygon with four sides. It has four right angles and parallel sides.
Find the area, perimeter and diagonal of a square with the given side 3.
Find the area. Area = (a)² = (3)² = 9.
Find the perimeter. Perimeter = 4(a) = 4 * 3 = 12.
Find the diagonal. Diagonal = (a)*(sqrt(2)) = 3 * 1.41 = 4.23. The above example will clearly illustrates how to calculate the Area, Perimeter and Diagonal of a Square manually.
This tutorial will help you dynamically to find the Math area problems.
