What is a square?
A square is a geometric shape that is a regular quadrilateral, meaning it has four equal sides and four equal angles. In a square:
- All four sides are of equal length.
- All four angles are right angles (90 degrees).
- The opposite sides are parallel.
Square formula:-
- Area of square = (side)² = a²
- Diagonal of square = √2 x side = a√2
- Perimeter of square = 4 x side = 4a meter
Example
Example.1:-Square side length = 20 cm, find the area, perimeter and diagonal of the Square.
Area of square = (side)² = (20)² = 400 cm²
Diagonal of square = √2 x side = √2 x 20 = 28.284 cm
Perimeter of square = 4 x side = 4 x 20 = 80 cm
Table of square
side(a) | Diagonal | Area | perimeter |
---|---|---|---|
1 | 1.414 | 1 | 4 |
1.5 | 2.121 | 2.250 | 6 |
2 | 2.828 | 4 | 8 |
2.5 | 3.536 | 6.250 | 10 |
5 | 7.071 | 25 | 20 |
