In geometry, a square is a regular quadrilateral. This means that it has four equal sides and four equal angles (90-degree angles)
Perimeter = 4 x a
The Area of a Square is the side length squared:
Area = a × a = a2
A square has a side length of a = 3 m, what is its Area?
Area = 3 m × 3 m = 9 m2
A square's perimeter, is the total distance around its edges.
Perimeter = 4a
A square has a side length of a = 5 m, what is its Perimeter?
Perimeter = 4 x 5 m = 20 m
Properties of Squares:
A square has four sides that are all the same length
All sides are equal in length
Each internal angle is 90°
Opposite sides are parallel
The diagonals are congruent
Be sure to use the same units for all measurements
